On young trees, eggs are deposited singly or occasionally in clusters of 3 to 4 on the shoots, stems and leaves, particularly the upper leaf surface. Concentrated around the growing shoots, eggs may occur at all heights on the host tree and are often placed in concealed locations such as leaf axils, leaf scars, veins, lenticels and fissures in the bark (Griffiths, 2001). Eggs laid on fruit are initially deposited singly on the fruit surface but are later laid in clumps of up to 12 among the frass and webbing associated with existing damage to the fruit (Griffiths, 2001). After three to five days, the eggs hatch and the larvae tunnel in the developing shoots of young trees and sometimes also feed upon the flowers, fruit and bark of host trees (Griffiths, 2001). A generation usually takes 1 to 2 months but may extend to five months if larvae enter diapause, which has been reported from areas of low temperature or rainfall, and occurs immediately after fruit-feeding despite apparently suitable climatic conditions (Griffiths, 2001). The caterpillars destroy the terminal shoot causing the tree to form many side branches and frequently a deformed trunk thereby significantly reducing the economic value of the timber (Griffiths, 2001). This species mainly attacks trees in areas with high light, hence the biggest effects are observed in young planted forests, particularly those planted with a single species (Nair, 2001). The borer is a problem to both nursery and planted stock; trees from three months to fourteen years in age and between 50 cm and 15 m in height have shown symptoms of Hypsipyla attacks (Griffiths, 2001). It has been one of the main factors preventing the ready establishment of mahogany plantations in many areas. While some methods can significantly reduce populations, this pest can cause significant damage even at low population levels and it is therefore considered a major destructive forest pest. Three main control methods are considered to control Hypsipyla species: silvicultural, chemical and biological. Silvicultural techniques applied to control Hypsipyla species include mixed or enrichment plantings, varying tree density, provision of shade, promoting vigourous tree growth in nurseries and plantations, and the selection of resistant or tolerant host trees. Previous attempts at biological control of Hypsipyla species have not been successful although research into possible agents continues. The most promising strategies for management of Hypsipyla species are integrated pest management programmes involving a combination of these techniques such as the use of pest tolerant host trees, planting of mixed stands and providing shade. While it typically attacks stressed or weakened trees it has been known to attack and cause the death of healthy trees of commercial importance. They are cylindrical, robust, shiny, brown or brownish-black beetles with erect yellow hairs protruding from the body. The head is covered by a thoracic shield and is not visible when viewed dorsally (Kimoto and Duthie-Holt, 2006). This beetle is named for the six spines or teeth found on each side of the posterior portion of the forewings (Cavey, Passoa and Kucera, 1994). After mating, each female constructs a longitudinal egg gallery, typically 15 to 35 cm long and 4 to 5 mm wide, and deposits eggs in individual niches along each side of the gallery. Pupation takes place in round chambers constructed at the ends of the larval galleries. Round exit holes measuring approximately 4 mm in diameter are apparent on the tree trunk after adults emerge (Kimoto and Duthie-Holt, 2006). This insect typically has two generations per year, one generation north of the Arctic Circle, with adult flight periods from April to May and July to August. It rarely attacks healthy, vigorously growing trees though it is capable of killing trees of commercial importance. Breeding attacks by Ips sexdentatus are characterized by the presence of reddishbrown frass on the bark surface of host trees, freshly cut logs or windthrow (Kimoto and Duthie-Holt, 2006). If healthy, vigourous trees are attacked, pitch tubes can be found on the main stem (Kimoto and Duthie-Holt, 2006). As with other conifer bark beetle species, Ips sexdentatus is a vector for blue-stain fungi (Ophiostoma spp. Transport of unprocessed logs, wood products, wooden packing materials, dunnage or pallets containing bark strips can provide a means of introduction of immature stages and adults. The posterior end of the forewings is completely covered with long hairs and also has four spines on each side, the third of which has a characteristic bulge at the top (Kimoto and Duthie-Holt, 2006). The larvae are white grubs with amber coloured head capsules that are typically 4 to 5 mm long when mature (Orlinski, 2004). Attacks are initiated by the males, who construct nuptial chambers under the bark, emit aggregation pheromones and are subsequently joined by 2 to 5 females (Kimoto and Duthie-Holt, 2006).
Though the webs are very unsightly, damage to most plants is considered to be insignificant if webs are removed soon after development. Fall webworm is most often discovered when the light gray, silken webs (Figure 12-12c) appear in the planting in June and July (1st brood) and August through September (2nd brood). Webworms enclose leaves (Figure 12-12a) and small branches (Figure 12-12b) in their silk nests. This distinguishes them from tent caterpillars, which make a smaller nest in the crotch of trees (Figure 12-3c). Webworm caterpillars, which are covered with long to yellowish tan hairs, remain inside webs; if food runs out, new foliage is encased. Yellownecked caterpillar (Datana ministra) occasionally results in outbreaks that may completely defoliate one or more plants. The remainder of the body is marked with four longitudinal yellow stripes interspersed with black, and the entire body is clothed with long, soft, white hairs (Figure 12-13b). Larvae feed in large colonies on leaves near the tips of twigs and branches (Figure 12-13a). Emerging caterpillars feed as a group, resulting in plant defoliation as caterpillars mature. Leafrollers, such as the obliquebanded leafroller (Choristoneura rosaceana) and redbanded leafroller (Argyrotaenia velutinana) can be found on blueberries. Obliquebanded leafroller larvae are green with dark heads and are about 25 mm (1 inch) long when fully grown. Redbanded leafroller larvae are small (up to 16 mm long) and green or pale yellow. Fall webworm Monitoring and Management Scout plants from late-June through September for webs. Do not burn or torch the nests while on bushes as this may do additional damage to the plants. Yellownecked caterpillar Monitoring and Management Scout every 2 weeks beginning in June or July. Leafrollers Monitoring and Management Leafrollers are usually controlled by natural enemies or by sprays applied for other pests. Trap information can be combined with growing degree-days to predict egg hatch, larval development, and optimal timing for control. First-generation larvae are active before and during bloom, and sprays for fruitworm typically control first generation leafrollers. The summer generation larvae are active during fruit ripening, feeding on fruit and foliage. Redbanded leafroller larvae may be present as soon as green foliage appears, and this first generation can injure leaves and young clusters. Whitemarked tussock moth (Orgyia leucostigma) does not cause significant feeding damage to mature bushes, but it can defoliate young blueberry plants. Larvae have irritating hairs, and the second generation can cause problems for pickers or contamination of harvested fruit. Female moths are white and flightless; they create a large egg mass wrapped inside a dried leaf that is typically stuck to a blueberry branch. Whitemarked tussock moth Monitoring and Management Prune out egg masses during winter. The first generation of this pest is typically controlled by insecticide sprays for cranberry and cherry fruitworm. Effective control early in the season usually avoids late-season problems with the larvae. Adult borers (9 to 18 mm long) emerge from mid-May through June and feed on the underside of the leaves along the mid-vein. In late-May to June, adult females lay eggs in new shoots several inches below a bud. Azalea Stem Borer Monitoring and Management In midsummer, look for infested twigs that are wilting, are breaking off at the base, have coarse sawdust-like frass at the base of the plant, or are dying. A history of azalea stem borers may require insecticide applications during the egg laying period (applied in mid-May and again in early June).

B C dieback of limbs, where a dark sunken canker may be observed on the outer bark, girdling the limb (85). On recent infections, the dry and desiccated dead leaves remain on the infected limb. Diagnosis of disease caused by Botryosphaeriaceae can be difficult based merely on observations of vascular and external symptoms. Accurate diagnosis by means of isolations and/or molecular techniques is required to confirm the presence of these species. The size, shape, and color of spores differ among species in the Botryospaheriaceae. It is recommended in all cases to conduct these activities during dry weather months of summer. This is especially important because the assemblage of canker pathogens differs among locations. It has been documented for avocado and grapevine that these conidia are released from pycnidia during periods of high humidity, and are then spread by rain splash and wind, typically between November and April (21,84). Diplodia agrifolia Hosts Damage and Importance Species in the Botryosphaeriaceae have a cosmopolitan distribution (85). In California, the importance and diversity of species in the Botryosphaeriaceae associated with branch cankers on multiple hosts are becoming better understood (70). They cause leaf spots, fruit rots, dieback, perennial cankers, and eventual death in economically important woody perennial crops and ornamental plants, as well as in both native and introduced forest tree species (22). Details for important pathogens in this family with respect to coast live oak are explained below. While it aggressively colonizes host tissue, the disease does not progress as aggressively as D. Management Strategies Given that botryosphaeriaceous taxa are only recently being recognized as important disease pathogens, few epidemiological studies have been conducted. Hence, the development and implementation of successful control methods have been limited, and this area of study is just beginning to be explored. Although great progress has been made throughout the last decade, management is still extremely Disease Cycle Conidia of D. Status Occurs in the coastal sites of the Nature Reserve of Orange County, as well as in Riverside and San Diego Counties. Throughout the Nature Reserve of Orange County, it was recovered from more plots and in higher frequencies than D. It was also recovered from Limestone Canyon, one of the inland sites in Orange County, suggesting an ability to establish within a broader range of environmental factors (43). It is difficult to model which factors contribute to the presence of this pathogen at this time (44). Long-term monitoring and further genetic studies will determine its distribution and impact. Nevertheless, we know that in California it occurs more frequently in Orange County (43), that it aggressively colonizes coast live oak seedlings (44), that its incidence has increased in San Diego and Riverside Counties within one year (46), and that it co-occurs with aggressive pathogens such as D. To minimize its impact on coast live oak, management of this pathogen is important. Symptoms Symptoms of bleeding and pycnidia formation, leaf desiccation, epicormic shoot formation, and tree death within three to four weeks have been observed on seedlings artificially inoculated with D. Thus far, trunk symptoms are more often observed in Riverside and San Diego Counties. Management Strategies Early detection and eradication will be the most important strategy for management of this new pathogen. Confirmation is essential for understanding the conditions 26 Oak Disease Management Nature Reserve of Orange County and Adjacent Wildlands 27 A B Damage and Importance Diplodia corticola is a known contributor to the decline of cork oak (Q. It has been shown that this pathogen is correlated to coast live oak mortality (46). At the time of this writing, Laguna Laurel had more dead trees and higher incidence of D.
Fat Embolism Fat embolism usually follows fracture of bones and other type of tissue injury. Although traumatic fat embolisms occur usually it is as symptomatic in most cases and fat is removed. But in some severe injuries the fat emboli may cause occlusion of pulmonary or cerebral microvasculature and fat embolism syndrome may result. Fat embolism syndrome typically begins 1 to 3 days after injury during which the raised tissue pressure caused by swelling of damaged tissue forces fat into marrow sinsosoid & veins. The features of this syndrome are a sudden onset of dyspnea, blood stained sputum, taccycardia, mental confusion with neurologic symptoms including irritability & restlessness, sometimes progress to delirium & coma. Air embolism Gas bubbles within the circulation can obstruct vascular flow and cause distal ischemic injury almost as readily as thrombotic masses. Generally, in excesses of 100cc is required to have a clinical effect and 300cc or more may be fatal. The bubbles act like physical obstructions and may coalesce to form a frothy mass sufficiently large to occlude major vessels. Amniotic fluid embolism It is a grave but un common, unpredictable complication of labour which may complicate vaginal delivery, caesarean delivery and abortions. The amniotic fluid containing fetal material enters via the placental bed & the ruptured uterine veins. The onset is characterized by sudden severe dyspnea, cyanosis, hypotensive shock followed by seizure & coma of the labouring mother. As discussed in this & the previous subtopics, the potential consequence of thromboembolic events is ischemic necrosis of distal tissue, known as infarction. Infarction Definition: An infract is an area of ischemic necrosis caused by occlusion of either the arterial supply or venous drainage in a particular tissue. The effect of such a dual blood supply is that if there is obsrtuction of one of the arterial supplies, the other one may offset the rapid occurrence of infarction in these organs unlike the renal & splenic circulations which have end arterial supply. Infarction caused by venous thrombosis is more likely to occur in organs with single venous outflow channels, such as testis &ovary. B: Rate of development occlusion Slowly developing occlusions are less likely to cause infraction since they provide time for the development of collaterals. Neurons undergo irreversible damage when deprived of their blood supply for only 3 to 4 minutes. D: Oxygen content of blood Partial obstruction of the flow of blood in an anaemic or cyanotic patient may lead to tissue infarction. Types of infarcts Infarcts are classified depening on: A) the basis of their colour (reflecting the amount of haemorrhage) into: 1. Anemic (White) infarcts B) the presence or absence of microbial infection into: 1. Red infarcts occur in: a) Venous occlusions as in ovarian torsion b) Loose tissues such as the lung which allow blood to collect in infarct zone. White infarcts occur in: a) b) Arterial occlusion in organs with a single arterial blood supply. Solid organs such as the heart, spleen, & kidney, where the solidity of the tissue limits the amount of hemorrage that can percolate or seep in to the area of ischemic necrosis from the nearby capillaries. Morphology of infarcts Gross: All infarcts are wedge-shaped with the occluded vessel at the apex and the periphery of the organ forming the base of the wedge. Following inflammation, some of the infarcts may show recovery, however, most are ultimately replaced with scars except in the brain. Microscopy: the dominant histologic feature of infarction is ischemic coagulative necrosis. The brain is an exception to this generalization, where liquifactive necrosis is common. Myocardial infarction Usually results from occlusive thrombosis supervening on ulcerating atheroma of a major coronary artery. Cerebral infarcts May appear as pale or hemorrhagic A fatal increase in intracranial pressure may occur due to swelling of large cerebral infarction, as recent infarcts are raised above the surface since hypoxic cells lack the ability to maintain ionic gradients & they absorb water & swell.
Brown rots digest cellulose within the heartwood and occasionally the sapwood of the plant, and leave behind lignin. Thus, the wood breaks down into reddish-brown cubes in advanced decay, with areas of white mycelium visible in the cracks between the cubes (83). Standing dead trees with brown rot, or live trees with fruiting bodies indicate extensive decay and high potential for stem breakage and tree failure (70). Management Strategies Please refer to "Management of Rots and Decay Fungi" in the "Best Management Practices Section" for an explanation of management strategies for this fungus. Other Diseases Hosts Phytophthora root rot (Phytophthora cinnamomi and other Phytophthora spp. As a decaying fungus, it plays an important ecological role by opening up the canopy in mature stands, creating cavities for wildlife habitat, and breaking down wood into important components of carbon sequestered in forest soil to improve soil moisture and Status P. It was not encountered during field surveys in Orange, Riverside, and San Diego Counties (43,45,46). Nature Reserve of Orange County and Adjacent Wildlands 45 44 Oak Disease Management Symptoms Fine root decay, bleeding cankers on the root crown and lower trunk. Removal of the outer bark layer reveals inner bark and cambium cankers, as seen with P. Trunk cankers typically originate below the soil or occasionally at the soil line, as opposed to those caused by P. Crown thinning and leaf yellowing are also observed in the crown, especially from the top-down. Phytophthora root rots are most common on ornamental oaks in well-irrigated landscapes. Disease Cycle Phytophthora species are fungus-like organisms, related to algae, and produce structures only visible under a microscope. Species of Phytophthora can survive in the soil for many years, and can be transmitted via movement of infested soil on equipment and shoes, and in infected or infested nursery stock (68). During high levels of soil moisture, especially prolonged periods of soil saturation, dormant spores (chlamydospores or oospores) may either form sporangia, or germinate to produce hyphae that can directly infect roots (68). Zoospores released from sporangia in the presence of free water are spread with splashing or flowing water. Following a chemotaxic gradient to find the roots of host plants, zoospores encyst and germinate hyphae, which infect and kill root cells. Sporangia can initiate Management Strategies the best management strategy is to prevent an introduction of these pathogens into non-infested areas. Maintain good sanitation practices described herein, especially when dealing with movement of soil. Know the source of nursery stock used in restoration projects, and screen soil for the presence of Phytophthora root rot, prior to deployment. Symptoms of crown thinning may be observed as old leaves senesce and drop from the canopy. Dry, thin, powdery fungal spots on the leaf surface of mature leaves may be observed. Morphological structures of Phytophthora cinnamomi including an oospore (a), chlamydospore (b), hyphae with hyphal swellings (c), and sporangia containing zoospores (d). Disease Cycle Oak powdery mildew is common in areas of high humidity and cool temperatures, especially near the coastline (17). Disease persists by production of asexual spores (conidia) during warm days and cool nights, and overwinters as cleistothecia or mycelium in infected buds (as with C. Ascospores produced in cleistothecia are released via wind during humid conditions. Host tissues are not killed as these fungi derive nutrition from living host cells via a fungal structure called haustoria (68). Dry conidia that form on superficial mycelium are dispersed via wind onto young shoots to initiate new infection (68).

The functions of the mind, the intellect, are those of affection, voluntary motions, etc. Innate directs the vital actions, those of the vegetative functions of the animal economy. Innate, the spiritual, has the power to conceive, judge and reason on matters, which pertains to the internal welfare of the body.

It represents the 5th cervical as being adjusted by the 3d and 4th fingers, instead of using the pisiform bone. The most of diseases are because of too much energy; not because nerve force is "shut off. The ear-marks show from what literature you have copied many of your false statements found in your booklet. What Moore would you have me do, That "crude adjustment" was not a "process stumbed onto. A direct nerve to the eye, direct from the spinal cord; another just as direct to the nose, one each to the teeth, throat, lungs, heart, stomach, liver, kidneys, bowels. This "illustrates how the brain communicates with all the organs through the nervous system. The Chiropractor states: "We have never intended to make this journal an instructive agent. The Developer of Chiropractic thinks it judicious and beneficial to use the columns of the Adjuster for that purpose, so as to keep the science within Chiropractic lines. Page 73: "To use the word treatment implies that something sick needs to be treated; that something which needs treating is something which is not normal, hence, disease. To treat, then, means to direct your attention, by any one of a thousand means to the diseased portions; to that place which is not normal; to that condition which is pathologically abnormal (1). Treatment, when resolved to its last analysis, means either stimulation or inhibition. In medicine there are stimulants; or in massage manipulation is designed and intended to stimulate; to excessively increase the present condition existing (5). In a case where we have only 80 per cent acting-a lack of function, the tendency of all therapeutical treatment is to make the 80 per cent, do the standard work of 100 per cent. By a subluxation of a vertebra we are producing pressure upon nerves, or reducing the calibre or carrying capacity of that nerve fibre; by so doing, interfering with transmission of cylic currents (7). If this pressure upon nerves be light; be steady, then function is excessive at periphery. If the pressure be heavy and permanent, then we have a lack of function at periphery. We have always assumed (9) the ground that we could because we have recognized the pathological states or conditions wherein there was an excess of function. The cause of normal heat is a normal amount of mental impulses; the cause of excessive heat must be an excessive amount of mental impulses. Let us assume the various states of excess of quantities or diminished quantities of electricity and see how the problem is deciphered. Let us go, in other words, from the known state of increased and diminished currents of electricity to the quantities that are present in excess or lack of in man. Page 79: "The entire rub of the proposition is that after the body has gone through such a burning-out process it dies for want of enough of the reparatory impulses to adapt itself to that standard" (12). I am pleased to see "disease is too much or not enough function," it being quite different from that found on page 78 of No. In diarrhoea, too much water with the stool either from a lack of function in the part of the kidneys, or too much on the part of the intestines. These abnormal conditions are because of nerve impingement-results of accidents or poisons. The freeing of nerves from impingement, the resumption of normal heat liquifies the thickened serum; and a surplus existing, it is discharged.
The underlying morphology includes foci of symmetric discoloration and sometimes softening with congestion, & punctate hemorrhage in the paraventricular region of the thalamus & Hypothalamus, in the mammillary bodies about the aqueduct in the midbrain, in the floor of the fourth ventricle and in the anterior cerebellum. The neurons may be relatively spared in the early stages but eventually reveal degenerative changes and eventually cell death. These are supposed to be due to thiamine deficiency as well, rather than ethanol direct toxicity. Peripheral Nerves the peripheral nerves suffer a demylinating polyneuropathy, occasionally mononeuropathy that is fairly common in chronic alcoholics who are malnourished. On the other hand a direct ethanol injury to myocardium will result in cardiomyopathy, which is discussed in the chapter that deals with heart diseases. Miscellaneous changes: Chronic alcohol intake has a tendency to produce hypertension even though in low doses alcohol (ethanol) tends to reduce blood pressure. Chronic alcoholics suffer higher incidence of acute & chronic pancreatitis and regressive changes in skeletal muscle referred as alcoholic myopathy. During pregnancy a condition known as fetal alcohol syndrome may 243 take place in infants whose mothers have been taking alcohol even as low as two to three drinks per day. The fetues can have microcephally, mental retardation, facial mal formation & cardiac defects at times. Increased risks of cancer of pharynx, larynx, esophagus, stomach, & possibly rectum & lung have also been encountered in chronic alcoholics. Physical injuries these are mainly classified in to four groups: injuries due to mechanical forces, changes in temperature, changes in atmospheric presence, and electromagnetic energy. A-Injuries due to mechanical forces Injuries due to mechanical forces are (1) soft tissue injuries, (2) bone injuries, (3) head injuries. Here we deal with soft tissue injuries, which are divided accordingly to their depth. Abrasion: this type of injury represents the most superficial type of skin injury, which involves the epidermal layer. It occurs when superficial epidermal cells are turnoff by friction or a glancing blow. There is no perforation of the skin & hence regeneration occurs with out scarring. Laceration versus incision Laceration is an injury over the skin which is an irregular tear produced by overstretching. The margins of a laceration are frequently hemorrhagic & traumatized and there will be bridging stands of tissues like blood vessels or fibrous tissues at the base. The margins are relatively clean and there are no bridging fibrous strands or tissues. An incision, in contrast to laceration, will be approximated by sutures to heal leaving no or little scar. Contusion this is an injury that is cause by a blunt force that injurs small blood vessels & causes intestinal bleeding usually with out a breach on the superficial tissue the bleeding will be evident if the contusion is on a superficial tissue but if it is in deeper structures like skeletal 244 muscles the bleeding will be evident after several hours or may remain obscured excepts the swelling & pain that is felt at the area over the contusion. Gunshot wounds Looking at the gunshot wounds give a very detailed story as to whether the shot is from a distance or, near by, or from a rifle or a handgun. It also tells the direction from which the bullets came & other important information for a forensic pathologist. The character of a gunshot wound at entry & exit and the extent of injury depend on the type of gun used, caliber of bullet, the type of ammunition, the distance of the firearm from the body, etc. There are also peripheral stippling of discrete, larger particles formed by the unburned powder, When the shot distance increases a beat only the stippling are present and at greater distances no gray black discoloration or stippling are present rather a wound smaller in size from the bullet and with narrow enclosing rim of abrasion is present. Cutaneous exit wounds are generally more irregular than the entry wounds due to the wobbling or trajectory motion of the bullet. In high velocity riffle bullets the exit wounds are larger and there are no stippling or dark discolorations. Large caliber, light velocity bullets cause extensive injury around the traversing wound due to the mass, velocity and motion of the bullet. Small caliber low velocity bullets cause a limited amount of injury to surrounding tissue. In general, it suffices to say that gun shot wounds tell a story to the experienced individual. B-Injuries related to changes in temperature Human beings are homoeothermic and their internal temperature must be maintained between 300C and 430C.
Since a female has 2 X chromosomes, she may be either homozygous or heterozygous for a mutant gene, & the mutant allele may demonstrate either dominant or recessive expression. Therefore, in heterozygous females carrying X-linked recessive mutations, some cells have one active normal X chromosome & other cells have an active abnormal X chromosome containing the mutant allele. Therefore, the heterozygous female expresses the disorder partially & with less severity than hemizygous men. Very rarely, the mutant allele may be activated in most cells & this results in full expression of a heterozygous X-linked recessive condition in the female. The male is, therefore, said to be hemizygous (& not heterozygous) for the X-linked mutant genes. Males have only oner X-chromosome, so they will clinically show the full phenotype of X-linked recessive diseases, regardless of whether the mutation produces a recessive or dominant allele in the female. Thus, the terms X-linked dominant or X-linked recessive refer only to the expression of the mutations in women. Mitochondrial inheritance is mediated by maternally transmitted mitochondrial genes, which are inherited exclusively by maternal transmission. Chromosomal disorders (Cytogenetic disorders) are caused by chromosome & genome mutations (i. They are found in 50% of early spontaneous abortuses, in 5% of stillbirths, & in 0. The normal karyotype Chromosome classification & nomenclature: Karyotype is the chromosome constitution of an individual. The term is also used for a photomicrograph of the chromosomes of an individual arranged in the standard classification. Karyotyping uses many types of techniques of which G-banding is the most common procedure. G-banding has the following steps:Arrest dividing cells in metaphase by using colchicine. The metaphase chromosomes will show alternating dark staining & lightstaining bands. About 400 -800 dark & light bands can be seen in a haploid set of chromosomes using G banding. And the first chromosome in such an arrangement is called chromosome 1, the 2nd chromosome is called chromosome 2, etc. Metaphase chromosomes are divided longitudinally into 2 sister chromatids held together at the centromere, which delineates the chromosome into a short arm (p) & a long arm (q). In a banded karyotype, each arm of the chromosome is divided into 2 or more regions. Each region is further subdivided into bands & sub bands which are also similarly numbered. Nomenclature of a chromosome showing the division of the long arm (q) of the chromosome into regions 1 & 2. Even though not shown in this figure, the other bands of this q arm & the p arm are similarly divided & numbered. The following order is used to describe karyotypes: First the total number of chromosomes is given. Types of chromosomal anomalies - Chromosomal anomalies may be numerical or structural. Structural anomalies are rearrangements of genetic material within or between chromosomes. In balanced structural anomalies, there is no change in the amount of essential genetic material whereas in the unbalanced ones segments. Trisomy is the presence of 3 copies of a particular chromosome instead of the normal 2 copies. Monosomy is the presence of only one copy of a particular chromosome instead of the normal pair.

These osseous unions are removed after Chiropractors replace the luxated vertebrae to their former and natural position. A mechanic is one who is skilled in the laws of motion and force, as applied to construction. There is this particular difference, however; Innate does not use tools or instruments to build or construct. In bow legs we find a corresponding flattering (Platycynemia) of the fibula to compensate and strengthen its fragile mate. He would study two bones, and by comparison, would find one normal and its opposite very much abnormal. Palmer, Discoverer and Developer of Chiropractic," a copy of which may be seen on page 917. Occasionally, when long bones are fractured, the fragments do not unite, the callus material is not supplied. Physicians try many expedients to make a union, but they experiment in vain, for they do not know why the osseous matter (symphysis material) is not supplied. Chiropractors who have studied the morbid anatomy of nerves would know why they did not supply the necessary material for uniting these fractures, and would be able to assist these useless repair nerves to their normal condition and usefulness. The delivery of the messages and their condition would be determined by the conductibility of the transferring tubes. A part or all of the skeletal frame may be softened by superheat (fever), a portion of the bone may ooze out, be deposited on the surface, causing morbid enlargement and ankyloses. When beat becomes less than normal, we find the third stage, that of hardening, consolidation, and eburnation; functions are performed in a less degree. Disease is but the performance of functions in either an excessive or deficient amount. Knowledge is gathered through the physical according as Innate is able to co-ordinate the spiritual with the material body. It is therefore necessary, in order to enhance our present and future existence to keep our bodies in proper condition. The voluntary are controlled by Educated, while others are more or less under the management of both. All cures made by Faith, Christian Science, Metaphysics, Charms, Mental Healers, Magnetics and Suggestions are produced by the Educated controlling Innate. Many persons in whom Innate is prerogative, assert themselves in thought over and above the Educated, compelling the mental to believe the possessor is ailing. Persons quite illiterate, by auto suggestion-self-hypnotized-will give a discourse on any given subject or compose poetry as fast as they can talk. Psychometry leads us into an undeveloped field of soul-life; it also explains first impressions on which fortune-tellers depend. Why not study nerves-the conveyors of impulses-and bones, the frame-work of the body, which, if disarranged impinge upon nerves and cause deranged functions-too much or not enough action. The time is coming when Innate will analyze its own condition and Educated will recognize that determination. It is said that those who never had sight never dream of seeing; those who were always deaf never dream of hearing. The transactions which make the deepest impressions, or those which occupy our minds the most, are the ones remembered when we awake. It is probable that only a very small part of our dreams are remembered when we rouse from sleep. I presume Innate is ever busy handling impressions received through the physical, as much so, as it is with the management of the vital functions. Circumstances dreamed, which would take many minutes or hours to accomplish, pass before the mind in a remarkably short space of time, as is proven by persons who were asleep but a moment or at the most a quarter of a minute; yet they dreamed of incidents that would have taken hours to perform had they really occurred. Occasionally dreams are of importance and systematic, giving us information upon subjects of which we were very much in need. This mysterious intercourse between Innate and Educated will in time be made more clear and taken advantage of.
