A sarcomere is the basic contractile unit of a muscle cell discount clarinex 5mg overnight delivery, repeating sarcomeres comprise a myofibril clarinex 5 mg without a prescription. As the muscle contracts buy clarinex 5 mg low cost, the Z-bands move closer together and the I-band and H-band shorten in length as the actin thin filaments are moved along the myosin thick filaments cheap clarinex 5 mg with visa. Why do smooth muscle fibers in cross section have different diameters and why do some of these fail to show nuclei? Since the cells interdigitate different diameters would be revealed in a particular plane of section and the plane of section does not always go through the nucleus discount 5mg clarinex overnight delivery. What is the functional significance of the cytoplasmic staining affinities of the basophilic erythroblast, polychromatophilic erythroblast, normoblast and erythrocyte? Basophilic erythroblast - ribosomes predominate for production of hemoglobin and transferrin receptors. The ventricle must create more force when contracting to deliver blood to the lungs (right ventricle) or the entire body (left ventricle), whereas the atrium only has to deliver blood to the ventricle. What types of capillaries are depicted on the covers of this manual and where might such capillaries be found? Front cover (fenestrated: endocrines, mucosa of gut, gall bladder) and inside the back cover (continuous: muscle, brain, lung) 10. The brush border increases the surface area, facilitating the reabsorption that occurs in the proximal tubule What is the functional significance of the occurrence of a brush border in the proximal tubule? Expanded apical surface maximizes reabsorption #49 Kidney, Human, H&E What are the components of the arterial portal system of the kidney? Afferent arteriole, glomerular capillaries, efferent arteriole What are the components of the blood urinary barrier in the glomerulus? Pituicytes (glia), endothelial cells #75 Pituitary, Human (Chrome-hematoxylin and Phloxin) What do Herring bodies represent? Catecholamines: Epinephrine (adrenaline) and norepinephrine (noradrenalin) What hormones regulate the function of the cortex? It allows for rapid and direct delivery of hypothalamic products with releasing and inhibiting effects on anterior pituitary cells 2. Raises serum calcium levels by acting on osteoblasts that in turn activate osteoclasts (release calcium from bone). Where is the principal site of storage and mobility acquisition of spermatozoa in the male reproductive system? Seminiferous tubules, tubuli recti, rete testis, ductuli efferentes, epididymis, ductus deferens, urethra. Tight junctions between Sertoli cells isolate developing sperm from the vasculature (prevent their immunological rejection). What are the fine structural specializations of ovarian cells involved with the production of steroid hormones? Impedes sperm entry except in peri-ovulatory period when the mucus in less viscous In what other regions of the body does one observe an abrupt junction between simple columnar and stratified epithelia? Fundamentally it consists of a chemical or physical method of killing the tissue and yet retaining characteristic peculiarities of shape and structure. Other techniques involve dehydration in alcohols and infiltration with paraffin, or some similar agent - a process called embedding. Sections 3 to 10 microns (3 to 10 thousandths of a millimeter) in thickness are cut on steel knives mounted in an instrument called a microtome, which has a precise mechanical advance. For electron microscopy the sections are considerably less than one ten-thousandth of a millimeter (0. This is accomplished by embedding the tissue in a plastic such as Epon or araldite (epoxy resins) and cutting on special ultramicrotomes equipped with a fine mechanical or thermal advance. This is especially important in determining whether an abnormality is an artifact of preparation or a pathologic process. In work with the light microscope, it is difficult to recognize the various components of cells and tissues without differential staining. The staining method can be altered to suit the needs of the examiner in order to accentuate certain tissues or organelles. Finally, in order to preserve the section which has been made from a block of fixed tissues and stained, it is mounted on a glass slide and covered with a thin cover glass by means of a transparent substance which hardens and seals the preparation to make it permanent.

This material is intended for educational use only by practicing health care workers or students and faculty in a health care field. We hope that it will be a good introduction to eye diseases for health science students working in Ethiopia. There are so many books about eye diseases available but hardly any, which are written from the perspective of Ethiopia, where more blind are live. The lecture note is basically focused on the community as well as clinical ophthalmology to introduce the students on the common causes and burden of blindness and their preventive aspect. So it is written for students who are intended to see patients and need to recognize each disease and recommend possible treatment. When looking at a patient with eye disease, the most important skill is to be able to recognize the appearance of each particular disease. In the management of diseases which are beyond their scope are recommended to refer as early as possible. Their main role is to pick problems early and to have an active role in the prevention of blindness. Selected pictures are used to illustrate some anatomical parts and common eye diseases to make note easier and understandable. There are several encouraging signs that there is an increasing awareness of the challenge of treatable and preventable blindness throughout the world. Our country is forming prevention of blindness to try to look realistically at the problem locally. In spite of all this, the number of avoidably blind people in Ethiopia continues to increase faster than the population. We would like to express our appreciation to The Carter Center, Atlanta Georgia for funding the activities in the development of this lecture note all the way through. We would like to thank Gondar University for helping us with different material in order to make this note feasible. Reviewers that highly contributed to the development of this material using their valuable time and experience include 1. Zeki Abdurazik, Assistant professor in Surgery, Gondar University At last but not least we would like to convey special appreciation for the finalization of the material at National reviewer level by using his valuable time Dr. The two eyes provide about half the total sensory input from the entire body into the brain. The eye is sensitive to trauma, infection or inflammation that may end up in blindness.

discount 5mg clarinex visa

Encorate order clarinex 5 mg with visa, Valparin generic clarinex 5 mg amex, Epilex) As per the new technology order clarinex 5mg visa, now slow release formulation drugs are available in Carbamazepine and Valproic acid e purchase clarinex 5mg amex. This helps to maintain adequate blood level all through out the day order clarinex 5 mg, by taking drugs only twice a day. In the last few years many new researches have been conducted on this disease and new drugs have been developed for effective control of Epilepsy. Newer Drugs : The second generation anti-epileptic drugs, now being used to treat patients not responding to conventional drugs include Gabapentin, Lamotrigine, Vigabatrine, Felbamate, Topiramate. Therefore, in patients not improving or having side effects with main conventional drugs, newer drugs should definitely be tried. Oxcarbazepine, Levitiracetam, Zonisamide have only recently been introduced and therefore, we have little experience with these drugs, but to date they have proved to be beneficial. If all these issues have been looked into and the relevant problems addressed, most of the seizures can be controlled. However the diagnosis needs to be individualized taking into consideration the patient’s age and his physical and mental condition and his social and financial background. Surgery : When drugs fail to control seizures and the cause of seizures is an electrical focus which may be localized to a structure, then seizures can be controlled after appropriate surgery. Hence, in refractory cases where a focus can be defined as a cause of epilepsy, surgery can fully control seizures in 30 to 35 % patients. A team of experienced Neurosurgeon - Neurophysician can decide as to which of the following surgeries would be beneficial to the patient. The parameters can be changed: For those patients who are not appropriate candidates for surgery, in whom a focus is not dependable or those who are awaiting surgery this method is beneficial, specially when anti-epileptic drugs have not worked. Targeted drug delivery), newer surgical techniques will ensure brighter future for epileptic patients. However in view of the ever changing concepts and advances in the field of medicine, this discussion should be adequate; if not complete. Misconceptions : Unfortunately a lot of misconceptions are still prevailing about Epilepsy; therefore it has been observed that the patients do not get the correct treatment. Even after recovering from epilepsy it is advisable to stay away from fire and not drive or swim for some years. Epileptic patients should be considered as normal; one should not have a biased attitude towards them. Julius Cesar, Napoleon, Alfred Nobel, Vincent Van Gaugh, Jhonty Rhodes, and many other great personalities suffered from epilepsy, but still managed to excel in their respective professions. To help the epileptic patients “The Indian Epilepsy Association and Society” have been very active in several cities. Various activities are carried out to provide moral support to the patient and family members, and to help patients gain acceptance in the society. It is really sad and surprising that there is very little awareness among the general public regarding this disease. Like heart attack, knowledge of the risk factors can prevent the occurrence of the disease in majority of cases. If the warning signs are identified in time, immediate safety measures can be taken easily, so that in future any major stroke can be averted. After a stroke it is essential that immediate diagnosis and correct treatment be given to prevent permanent disabilities. This is the main aim behind providing detailed information of paralysis (brain stroke) in this chapter. Paralysis can occur due to obstruction in the blood circulation in the main arteries supplying blood to the brain. Due to the obstruction of some of the arteries of the brain, the blood circulation is affected leading to reduced nutrition and oxygen to brain cells, which hampers the normal working of these brain cells leading to a stroke. In 30% of these kind of patients there is a possibility of getting a bigger stroke attack in next five years. Thus, this serves as a warning for such patients to take good care of themselves in order to avoid future strokes. The doctors evaluate the extent, type and location of the damage to the brain on the basis of the signs and the severity of the paralytic attack. If the left side of the brain is affected then the right side of the body is paralyzed, and usually speech is also affected. Similarly, if the right side of the brain is affected, the left Main 4 Arteries Supplying Blood to the Brain side of the body gets paralyzed. The two arteries in the anterior portion of the neck are called the Carotid arteries and the arteries in the posterior part of the neck are called the vertebral arteries, which provide uninterrupted blood supply to the brain.
