1 Mites live naturally on dogs, but any mite in sufficient quantity can cause skin problems.  Two common types of mites that can cause mange are Demodex canis, which causes demodectic mange, and Sarcoptes scabei, which causes sarcoptic mange.
Ad. One area in which osmoreceptors are found is in the brain, specifically inside the hypothalamus. They regulate the amount of vasopressin, a hormone which tells the kidneys to retain water, which is expressed by the hypothalamus.
2.3.3 Central Chemoreceptors. The central chemoreceptors are located near the ventral surface of the medulla close to the site of exit of the 9th and 10th cranial nerves. They primarily respond to changes in [H + ] in the adjacent brain ECF.n pathological situations if the chemoreceptor cells are hypoxic enough to cause some local lactic acidosis, this increase in [H + ] can also stimulate the central chemoreceptors. Severe hypoxia though will soon disrupt neuronal function and will prevent any response.
