Document Summary
18. 5 appetite control: appetite is the drive that compels us to seek food several types of interacting hormones control appetite by affecting part of the hypothalamus called the arcuate nucleus. Suppresses appetite and increase metabolic rate after eating: secreted from adipocytes inhibits release of the hypothalamic neurotransmitter neuropeptide y (negative feedback, low leptin levels depleted fat storage. Ghrelin enhances appetite: secreted from the stomach simulate the release of neuropeptide y, gastric bypass surgery decreased ghrelin secretion. 18. 6 vitamins: vitamins are organic compounds that are required in small amounts for normal metabolism that body cells cannot synthesize in adequate amounts. A antioxidant necessary for synthesis of visual pigments, mucoproteins, and mucopolysaccharides; for normal development of bones and teeth; and for maintenance of epithelial cells. D promotes absorption of calcium and phosphorus, ensuring that adequate amounts of these minerals are available in the blood for tooth and bone formation and metabolic processes (in intestine)
