Drowning
37. mosquito bite is the cause of
Plague
Leishmaniasis

Substance P
Dopamine
GABA
Enkephalin
The pain information in the CNS is controlled by ascending and descending inhibitory systems, using endogenous opioids, or other endogenous substances like serotonin as inhibitory mediators. In addition, a powerful inhibition of pain-related information occurs in the spinal cord. Enkephalins are small peptides that can serve as neurotr mitters in the brain. Enkephalins act to attenuate substance P release in the dorsal horn of the spinal cord and inhibit afferent pain fibers

Metabolic acidosis uncompensated
Respiratory acidosis compensated
Respiratory acidosis uncompensated
Respiratory alkalosis occurs when a person breathes too fast or too deep and carbon dioxide levels drop too low. This causes the pH of the blood to rise and become too alkaline. When the person inhales too much CO2 blood becomes acidic, respiratory acidosis occurs. To compensate that ,levels of H2CO3 increases or decreases. If no change in level occurs it is called uncompensated.

Which artery is causing this problem:
Anterior cerebral artery
Middle cerebral artery
The MCA is by far the largest cerebral artery and is the vessel most commonly affected by cerebrovascular accident. The MCA supplies most of the outer convex brain surface, nearly all the basal ganglia, and the posterior and anterior internal capsules. Infarcts that occur within the vast distribution of this vessel lead to diverse neurologic sequelae. Understanding
these neurologic deficits and their correlation to specific MCA territories has long been researched.
Posterior cerebral artery
Middle meningeal artery 58. Low oxygen level detected by
carotid body
The carotid body functions as a sensor: it responds to a stimulus, primarily O2 partial pressure.The carotid sinus contains numerous baroreceptors for maintaining blood

Smoking causes the mucus-secreting ciliated pseudostratified columnar respiratory epithelial cells that line the airways to be replaced by stratified squamous epithelium, or a stone in the bile duct that causes the replacement of the secretory columnar epithelium with stratified squamous epithelium (Squamous metaplasia). Metaplasia is an adaptation that replaces one type of epithelium with another that is more likely to be able to withstand the stresses it is faced with.

Preload
preload is the end diastolic volume that stretches the right or left ventricle of the heart to its greatest dimensions under variable physiologic demandVenous return (VR) is the flow of blood back to the heart. Increased pulmonary venous return to the left atrium leads to increased filling (preload) of the left ventricle, which in turn increases left ventricular stroke volume by the Frank-Starling mechanism

Medial longitudinal arch
The medial arch isismade up by the calcaneus and higher than the lateral longitudinal arch.
Its weakest part (i.e., the part most liable to yield from overpressure) is the joint between the talus and navicular, but this portion is braced by the plantar calcaneonavicular ligament a.k.a. spring ligament, which is elastic and is thus able to quickly restore the arch to its original condition when the disturbing force is removed.

Heparin
Warfarin
Plasminogen
Plasmin is released as a zymogen called plasminogen (PLG) from the liver into the systemic circulation. Plasmin is a serine protease that acts to dissolve fibrin blood clots. Apart from fibrinolysis, plasmin proteolyzes proteins in various other systems: It activates collagenases, some mediators of the complement system, and weakens the wall of the Graafian follicle, leading to ovulation. It cleaves fibrin, fibronectin, thrombospondin, laminin, and von Willebrand factor. Plasmin, like trypsin, belongs to the family of serine proteases.

79. Sympathetic nerve system will cause:
Decrease heart rate
Increase bronchial diameter
The bronchial branches contain smooth muscle which is under the control of the autonomic (automatic) nervous system. Stimulation from the sympathetic division of the autonomic nervous system causes these smooth muscles to relax, dilating the bronchial branches allowing more air to pass through the lungs. sympathetic nervous system is stimulated to prepare the body for immediate action. In the case of the lungs, this me allowing more air through so that more oxygen will be available for muscle contraction
Miosis
Lacrimation
