About 100 billion neurons in human brain Neurons are somewhat like trees, but are laid end to end. Axon terminal/terminal buttons: the very end, where small fibers come out of the axon. Many drugs affect neurotransmitters, such as causing certain ones to be released, released more often, or not to be released at all. Neural Transmission the neuron contains charged ions that flow in and out of the axon to create energy to transmit a message Resting potential ­ when a neuron is not currently sending a message Action Potential ­ brief electrical charge when message is sent Refractory period ­ small down time when a neuron cannot fire again All or none principle ­ a neuron can either fire or not. There is no partial firing Threshold ­ in order to fire you have to meet a minimum activity point.

Results- Almost normal function, except when it came to input coming only from 1 source. Researchers find the damage and see what effects it is having on the rest of the body. However, the brain can reroute itself, and find new pathways to access information and restore some function. All sorts of sensation areas have been mapped out, as well as radical behavioral changes (mostly in animals). This magnet aligns atoms in our brain, then a brief radio wave distorts the atoms, when the atoms return to their normal spin they release signals that provide detailed pictures of the brain.

Roundworms, whipworms and hookworms are also spread when faeces are used as fertiliser. Other people in the village and especially children playing on the ground become infected with the eggs. Like the other parasites, hookworms are spread when an infected person does not use a latrine but defecates outside. Hookworm larvae can enter the body through any part that comes in contact with infected soil, although most often they penetrate the skin of the feet. In the body they travel through the lungs to the intestine, where they will grow into adults.

These spinal level motor patterns may occur in patients with severe brain injuries or even brain death the treatment 2014 online carbidopa 300mg online. Failure to withdraw on one side may indicate either a sensory or a motor impairment medications you cant take while breastfeeding buy cheap carbidopa 110 mg on line, but if there is evidence of facial grimacing symptoms 0f pregnancy discount carbidopa 125 mg free shipping, an increase in blood pressure or pupillary dilation medicine 8 pill purchase 125 mg carbidopa with mastercard, or movement of the contralateral side, the defect is motor. Failure to withdraw on both sides, accompanied by facial grimacing, may indicate bilateral motor impairment below the level of the pons. Posturing responses include several stereotyped postures of the trunk and extremities. Most appear only in response to noxious stimuli or are greatly exaggerated by such stimuli. Seemingly spontaneous posturing most often represents the response to endogenous stimuli, ranging from meningeal irritation to an occult bodily injury to an overdistended bladder. The nature of the posturing ranges from flexor spasms to extensor spasms to rigidity, and may vary according to the site and severity of the brain injury and the site at which the noxious stimulation is applied. In addition, the two sides of the body may show different patterns of response, reflecting the distribution of injury to the brain. Clinical tradition has transferred the terms decorticate rigidity and decerebrate rigidity from experimental physiology to certain patterns of motor abnormality seen in humans. First, these terms imply more than we really know about the site of the underlying neuro- logic impairment. Even in experimental animals, these patterns of motor response may be produced by brain lesions of several different kinds and locations and the patterns of motor response in an individual to any one of these lesions may vary across time. In humans, both types of responses can be produced by supratentorial lesions, although they imply at least incipient brainstem injury. There is a tendency for lesions that cause decorticate rigidity to be more rostral and less severe than those causing decerebrate rigidity. In general, there is much greater agreement among observers if they simply describe the movements that are seen rather than attempt to fit them to complex patterns. Flexor posturing of the upper extremities and extension of the lower extremities corresponds to the pattern of movement also called decorticate posturing. The fully developed response consists of a relatively slow (as opposed to quick withdrawal) flexion of the arm, wrist, and fingers with adduction in the upper extremity and extension, internal rotation, and vigorous plantar flexion of the lower extremity. However, decorticate posturing is often fragmentary or asymmetric, and it may consist of as little as flexion posturing of one arm. Such fragmentary patterns have the same localizing significance as the fully developed postural change, but often reflect either a less irritating or smaller central lesion. The decorticate pattern is generally produced by extensive lesions involving dysfunction of the forebrain down to the level of the rostral midbrain. A similar pattern of motor response may be seen in patients with a variety of metabolic disorders or intoxications. For example, in the series of Jennett and Teasdale, after head trauma only 37% of comatose patients with decorticate posturing recovered. Some patients assume an opisthotonic posture, with teeth clenched and arching of the spine. Tonic neck reflexes (rotation of the head causes hyperextension of the arm on the side toward Examination of the Comatose Patient 75 which the nose is turned and flexion of the other arm; extension of the head may cause extension of the arms and relaxation of the legs, while flexion of the head leads to the opposite response) can usually be elicited. As with decorticate posturing, fragments of decerebrate posturing are sometimes seen. These tend to indicate a lesser degree of injury, but in the same anatomic distribution as the full pattern. It may also be asymmetric, indicating the asymmetry of dysfunction of the brainstem. Although decerebrate posturing usually is seen with noxious stimulation, in some patients it may occur spontaneously, often associated with waves of shivering and hyperpnea. Decerebrate posturing in experimental animals usually results from a transecting lesion at the level between the superior and inferior colliculi. The level of brainstem dysfunction that produces this response in humans may be similar, as in most cases decerebrate posturing is associated with disturbances of ocular motility. However, electrophysiologic, radiologic, or even postmortem examination sometimes reveals pathology that is largely confined to the forebrain and diencephalon. Thus, decerebrate rigidity is a clinical finding that probably represents dysfunction, although not necessarily destruction extending into the upper brainstem.

The venous sinuses warm incoming air and are especially prominent in the lamina propria that covers the middle and inferior conchae symptoms 7dpiui discount carbidopa 110mg without prescription. The deep layers of the lamina propria fuse with the periosteum or perichondrium of the nasal bones and cartilages symptoms 4dp5dt buy carbidopa 110mg, and at these sites medicine used for anxiety carbidopa 125 mg online, the nasal mucosa forms a mucoperiosteum or mucoperichondrium symptoms 38 weeks pregnant buy cheap carbidopa 300mg online, respectively. The surface of the epithelial lining is bathed by a thin film of mucus that constantly is moved toward the pharynx by the action of the ciliated epithelial cells. The mucus is derived from surface goblet cells and secretions from mucoserous glands in the lamina propria. The mucous layer contains IgA and other immunoglobulins that protect against local infection. IgA is produced by plasma cells within the lamina propria and is taken up by secretory cells of adjacent glands. The IgA is then coupled to the secretory component of these cells, transported, and secreted onto the surface of the nasal mucosa. The same type of mucosa extends into the paranasal sinuses, but here the epithelium is thinner, there are fewer goblet cells, the lamina propria is thinner and contains fewer glands, and venous sinuses are absent. The paranasal sinuses (maxillary, sphenoid, frontal, ethmoid) lie within bones of the same name surrounding the nasal cavity and are continuous with it through small openings. Although cilia of the lining epithelium within the paranasal sinuses generally beat toward the nasal cavity, the ciliated epithelial cells are coordinated in such a way that the pathway ciliary motion follows is a large, open spiral, the pitch of which narrows at the opening to the nasal cavity. It also is a pseudostratified columnar epithelium, but it lacks goblet cells and is much thicker than the respiratory lining epithelium. Three primary cell types are present: supporting cells, basal cells, and sensory or olfactory cells. Supporting (sustentacular) cells are tall with narrow bases and broad apical surfaces that bear long, slender microvilli. Apically, welldeveloped junctional complexes join the supporting cells to adjacent olfactory cells. They are spindle-shaped with rounded nuclei located centrally in an expanded area of cytoplasm. Apically, the cell tapers to a single slender process (a modified dendrite) that extends between the supporting cells to reach to the surface, where it expands into a bulblike olfactory vesicle (knob). Six to eight long olfactory hairs extend from the olfactory vesicle and pass parallel to the surface of the epithelium, embedded in a film of fluid. The olfactory hairs are modified, nonmotile cilia that act as the excitable component of these cells. For a short distance from their origins, the olfactory hairs have a typical ciliary structure but then narrow abruptly, and the microtubules decrease in number and change from doublets to singlets. Basally, the olfactory cells narrow to a thin process, an axon, that passes into the lamina propria, where, with similar fibers, it forms small nerve bundles. Odorants (airborne substances which stimulate olfactory sensory neurons) bind with a nasalspecific protein called olfactory binding protein which aids in binding the odorant molecules to receptors located in the plasmalemma of olfactory cilia. Odorant receptors are G-protein coupled seven transmembrane molecules that are capable of detecting and discriminating among thousands of specific molecules. Basal cells are short, pyramidal cells crowded between the bases of sustentacular and olfactory cells. They are undifferentiated cells that give rise to either of the other two types of cells. The olfactory cells are unique among neurons in that they are in direct contact with the external environment and, unlike other neurons, constantly are replaced every 30 to 60 days. Between the luminal surface and the basal cells lie variable numbers of progressively more differentiated receptor neurons, accounting in part for the thickness of the olfactory epithelium. Rich plexuses of blood vessels and branched, tubuloacinar serous glands are present in the lamina propria. The glands are the olfactory glands (of Bowman), whose watery secretions flush the surface of the olfactory epithelium to prevent continuous stimulation by a single odor and also serve as a solvent for odorant materials.

The central choriocapillary layer consists of a net of capillaries lined by a fenestrated endothelium; these vessels provide for the nutritional needs of the outer layers of the retina medications may be administered in which of the following ways order carbidopa 110 mg amex. Ultrastructurally it shows five separate strata made up of basal laminae of capillaries in the choriocapillary layer medications known to cause pancreatitis buy carbidopa 300 mg free shipping, the pigment epithelium of the retina treatment 6th feb cardiff carbidopa 125 mg visa, and between them treatment for hemorrhoids purchase carbidopa 110 mg with amex, two thin layers of collagen separated by a delicate elastic network. It forms a thin triangle when seen in section with the light microscope and consists of an inner vascular tunic and a mass of smooth muscle immediately adjacent to the sclera. The internal surface is covered by ciliary epithelium, a continuation of the pigment epithelium of the retina that lacks photosensitive cells. Ciliary epithelium consists of an inner layer of nonpigmented cells and an outer layer of pigmented cells, each resting on a separate basal lamina; it is unusual in that the cell apices of both layers are closely apposed, apex-to-apex. The outer pigmented cell layer is separated from the stroma of the ciliary body by a thin basal lamina continuous with that underlying the pigment epithelium in the remainder of the retina. The basal lamina of the nonpigmented layer lies adjacent to the posterior chamber of the eye and is continuous with the inner limiting membrane of the retina. Uveal Layer the uvea, the middle vascular coat of the eye, is divided into choroid, ciliary body, and iris. Its outer surface is connected to the sclera by thin avascular lamellae that form a delicate, pigmented layer called the suprachoroid lamina. The lamellae mainly consist of fine elastic fibers between which are numerous large, flat melanocytes and scattered macrophages. The lamellae cross a potential cleft, the perichoroidal 275 the basal plasmalemma of the nonpigmented cells shows numerous infoldings and is involved in ion/fluid transport. The cells contain numerous mitochondria and a well-developed, supranuclear Golgi complex. The adjacent pigmented cells of the outer layer also show prominent basal infoldings, and the cytoplasm is filled with melanin granules. The apices of cells of the inner, nonpigmented epithelium are united by well-formed tight junctions that form the anatomic portion of the bloodaqueous barrier, which selectively limits passage of materials between the blood and the interior of the eye. The ciliary epithelium elaborates aqueous humor, which differs from blood plasma in its electrolyte composition and lower protein content. Aqueous humor fills the posterior chamber, provides nutrients for the lens, and posteriorly, enters the vitreous humor. Anteriorly, it flows from the posterior chamber through the pupil into the anterior chamber and aids in nourishing the cornea. In its anterior part, the inner surface of the ciliary body is formed by 60 to 80 radially arranged, elongated ridges called ciliary processes, which are lined by ciliary epithelium and contain a highly vascularized stroma and scattered melanocytes. Zonule fibers, which hold the lens in place, are produced mainly by the nonpigmented cell layer of the ciliary epithelium and are attached to its basal lamina. Most of the ciliary body consists of smooth muscle, the ciliaris muscle, which controls the shape and therefore the focal power of the lens. The muscle cells are organized into regions with circular, radial, and meridional orientations. Numerous elastic fibers and melanocytes form a sparse connective tissue between the muscle bundles. The ciliaris muscle is important in eye accommodation, and when it contracts, it draws the ciliary processes forward, thus relaxing the suspensory ligament (zonule fibers) of the lens, allowing the lens to become more convex and to focus on objects near the retina. The iris is continuous with the ciliary body at the periphery and divides the space between the cornea and lens into anterior and posterior chambers. The anterior chamber is bounded anteriorly by the cornea and posteriorly by the iris and central part of the lens. The posterior chamber is a narrow space between the peripheral part of the iris in front and the peripheral portion of the lens, ciliary zonule, and ciliary processes. The margin attached to the ciliary body forms the ciliary margin; that surrounding the pupil is the pupillary margin. The stroma of the iris consists primarily of loose, vascular connective tissue with scattered collagenous fibers, melanocytes, and fibroblasts embedded in a homogeneous ground substance. The anterior surface lacks a definite endothelial or mesothelial covering but is lined in part by a discontinuous layer of melanocytes and fibroblasts.
