A hollow cylinder called the periosteal collar forms through intramembranous ossification around the middle of the cartilage model purchase genuine trazodone on-line. The primary center of ossification begins with calcification of matrix at the diaphysis and eroding by blood vessels discount trazodone 100 mg free shipping. The osteoprogenitor cells differentiate into osteoblasts and begin depositing matrix purchase generic trazodone online, forming spicules. Secondary centers of ossification begin in the epiphysis at each end with invasion by blood vessels 22 23 Growth at the epiphyseal plate: Passing from the articular end of the cartilage toward the ossification center of the diaphysis, the following zones are encountered in succession in the growth plate: 1) zone of reserve cells: A thin layer (3-6 cells wide) of small, randomly oriented chondrocytes adjacent to the bony trabeculae on the articular side of the growth plate. Mitotic figures are present and the axis of the mitotic figure usually is perpendicular to that of the row of chondrocytes. In the epiphyses where growth in length is occurring, note the zones of reserve cells, proliferation, maturation, hypertrophy, calcification, ossification and resorption. The zone of endochondral ossification spreads from the primary ossification center toward the ends of the cartilage. Recall that this bone is growing in width by apposition and remodeling along the periosteum and the endosteum. This increase in length and extension of the primary ossification center results in a sequence of changes in the chondrocytes of the epiphyses, which is similar to that described for the establishment of the primary center. In the epiphyseal growth plate, observe the zones of reserve cells, proliferation, maturation, hypertrophy, calcification, ossification and resorption. When growth ceases, the epiphyseal disk is entirely replaced by spongy bone and marrow (“closure of the epiphyses”), resulting in a visible epiphyseal line. In synovial or diarthrodial joints, articular cartilage caps the ends of the bones, which are kept apart by a synovial cavity filled with synovial fluid. The articulation is enclosed by a dense fibrous capsule, which is continuous with the periosteum over the bones. Internal to this is the synovium, a secretory membrane formed by a layer of collagenous fibers interspersed with flattened fibroblasts (synovial cells). The connective tissue elements include the meninges, which surround the central nervous system; capsules surround some sense organs and ganglia; and the endo-, peri-, and epineurium of peripheral nerves. Meninges Dura mater Arachnoid mater Grey matter Subarachnoid space Cerebral cortex Pia mater White matter 26 The detailed structure and function of the nervous system will be studied during the neurosciences course. The following class slides and electron micrographs will serve to acquaint you with nervous tissue as one of the four basic tissues. Spinal cord #85 Spinal Cord, Cross section (Nissl stain) At low power identify the centrally located butterfly or H- shaped arrangements of the gray matter. Identify the white and gray matter, and the dorsal (posterior) and ventral (anterior) horns of the gray matter. With medium magnification, identify the cell bodies of the large motor neurons in the anterior horn of the gray matter. Within the white matter, note the nuclei of glial cells (mostly oligodendroglia) and the cross sections of axons (unstained). Surrounding the gray matter is the paler staining white matter and the supporting cells (oligodendroglia and others). In the gray matter, note the size and shape of the cell body of the neurons, particularly those in the anterior (ventral) horn. With the Cajal technique, silver is precipitated on neurofilaments within neuronal cell bodies and their processes. In contrast, most of the axons of the white matter are viewed in cross section, since the fibers are running to and from the brain and other segmental levels of the spinal cord. Brain #86 Cerebellum, H&E Observe the pale staining branches of the central white matter surrounded by a darkly stained cortex. Identify the outer, pale-staining molecular layer of the cerebellar cortex, and the inner, basophilic granular layer of the cortex. The molecular layer contains axons and dendrites, but relatively few neurons compared to the granular layer. On these sections of the cerebellum, the cut surfaces may result in the exposure of the pale- staining medulla (white matter) at the surface of the section, where it could be confused with the molecular layer of the cortex. Try to find a surface covered by the meninges, to insure that you are indeed looking at the cortical surface. With medium power magnification, examine the junctional zone between the molecular and granular layers of the cortex. The basophilic nuclei of the granular layer, which superficially resemble lymphocyte nuclei, belong to granule cells. Axons of these cells (not visible with H&E) extend into the molecular layer and relay neural information to this layer. The cortex, itself, is divided into 6 layers, not all of which are clearly distinguishable in this slide. Note the similarity of the large pyramidal cells to the large motor neurons in the ventral horn of the spinal cord. With medium power, identify the neuronal cell bodies and their eccentric nuclei with prominent nucleoli. Although no slide is suggested for study of a parasympathetic ganglion, these will be seen in many organs (e. Preganglionic axons in both sympathetic and parasympathetic systems are myelinated while postganglionics are unmyelinated. It contains glia like the central nervous system, however there are no Schwann cells, fibroblasts or other connective tissue elements within the ganglia. In the cross section note the axon (black), which is surrounded in turn by a myelin sheath and its Schwann cell neurilemma (brown). Muscle is especially adapted for contractility with elongated cells arranged in parallel to the direction of contraction. Blood vessels within the associated connective tissue supply a rich blood supply to provide nutrients and oxygen and to eliminate waste products. The term "fiber" is used here in contrast to a connective tissue fiber, which is non-cellular, and to a nerve fiber which is a cell process. Its plasma membrane (which is not visible with the light microscope) is often called the sarcolemma and its cytoplasm is given a special name, sarcoplasm. Skeletal and cardiac muscle fibers have a characteristic striated appearance due to the organization of myofilaments. In smooth muscle fibers the myofilaments are not arranged with regularity and so these cells are nonstriated. The most striking feature of skeletal muscle fibers is the presence of striations, which are visible in longitudinally sectioned fibers.

Loop diuretics: Loop diuretics like frusemde inhibit Na - K – 2Cl symporter in the ascending limb order trazodone. Adverse effects: Hypokalemia buy cheap trazodone online, nausea buy discount trazodone on line, anorexia, vomiting epigastric distress, fatigue weakness muscle cramps, drowsiness. Therapeutic uses: acute pulmonary edema, edema of cardiac, hepatic and renal disease. Hypertension, cerebral edema, in drug overdose it can be used to produce forced diuresis to facilitate more rapid elimination of drug. Potassium sparing diuretics mechanism of action: Potassium sparing diuretics (spironolactone, triamterene, amiloride) are mild diuretics causing diuresis by increasing the excretion of sodium, calcium and bicarbonate but decrease the excretion of potassium. Hyponatraemia 65 Therapeutic uses: used with conjunction with thiazides or loop diuretics in edema due to, cardiac failure nephrotic syndrome and hepatic disease. Carbonic anhydrase inhibitors: these drugs like acetazolamide inhibit the enzyme carbonic anhydrase in renal tubular cells and lead to increased excretion of bicarbonate, sodium and potassium ions in urine. Main adverse effects of these agents are drowsiness, hypokalemia, metabolic acidosis and epigastric distress. Osmotic diuretics: these drugs like mannitol and glycerine (glycerol) are freely filtered at the glomerulus and are relatively inert pharmacologically and undergo limited reabsorption by renal tubule. These are administered to increase significantly the osmolality of plasma and tubular fluid. Drugs used in hypotensive states and shock Antihypotensive drugs or agents are used to elevate a low blood pressure and may be classified as follows: I. Vasoconstrictor drugs these include: • Peripherally acting vasoconstrictors which are further divided into sympathomimetic drugs and direct vasoconstrictors. Sympathomimetics used to elevate the blood pressure include adrenaline, noradrenaline, methoxamine, phenylephrine, mephentermine and ephedrine. Treatment of shock Shock is a clinical syndrome characterized by decreased blood supply to tissues. Common signs and symptoms include oliguria, heart failure, disorientation, mental confusion, seizures, cold extremities, and comma. They play important roles in physiologic processes and also have several pharmacological significances. Histamine It is a potent tissue amine widely distributed in plant and animal tissues and in the venoms of bees. In man, it is formed by decarboxylation of histidine and major portion is stored in mast cells and basophils. Stimulation of H1 receptors results in smooth muscle contraction, increased vascular permeability, and mucus production. Activation of H2 receptors increases gastric acid production, and this effect is blocked by H2 blockers such as cimetidine. Cardiovascular system Histamine produces dilatation of capillaries and venules accompanied by a fall in blood pressure. This effect cannot be adequately reversed by antihistaminic agents but by adrenaline. Smooth Muscles: Histamine directly stimulates the smooth muscles of various tissues including the bronchi and uterus. But it plays very important role in anaphylaxis and other forms of allergic reactions. Its release may be induced by various agents including certain venoms, drugs, trauma (thermal, chemical, radiation), and antigen-antibody reactions. Adrenaline has actions opposite to those of histamine and thus acts as a physiological antagonist. Other supportive measures include administration of oxygen and artificial respiration if necessary. Antihistaminic drugs are not able to counteract the hypotension and brochospasm characteristic of anaphylactic shock. Antihistaminc Drugs These drugs competitively block histamine receptors and are of two types: 1. H2 receptor antagonists (used in the treatment of acid-peptic disease) H1 Receptor Antagonists Classification of H1 recepror antagonists: 1. Other Effects: are independent of the antihistaminic effects and vary widely according to the drug used. Anti-motion sickness effects are exhibited by promethazine, diphenhydramine, and dimenhydinate. Some have central antimuscarinic actions which is useful in the treatment of Parkinsonism. Pharmacokinetics: They are well-absorbed following oral and parenteral administration. And are mainly metabolized by the liver; degradation products are removed in the urine. Allergic Disorders:-Including urticaria, seasonal hay fever, atopic and contact dermatitis, mild blood transfusion reactions. Their topical use is not recommended because of the risk of sensitization and a high tendency to cause eczematous reactions. Dimehydrinate and promethazine are employed in the prevention and treatment of motion sickness, other vomiting disorders associated with labyrinthine dysfunction as well as nausea and vomiting associated with pregnancy. Diphenhydramine is frequently used in the treatment of cough as combination preparation with other agents. Highest concentration in mammals is found in the pineal gland, acting as a precursor for melatonin. It is synthesized from the amino acid tryptophan and acts on several types of receptors. Altered functions may be responsible for disturbances in sleep, mood, sexual behavior, motor activity, pain perception, migraine, temperature regulation, endocrine control, psychiatric disorders and extra-pyramidal activity. It relieves the nausea and vomiting, but the headache may recur, necessitating repeated administrations. The bioavailability of oral dose is only 14 %; thus, the oral dose is several times larger than the subcutaneous dose.
