The short-term response to stress occurs faster than the long-term response to stress because Select one: a. epinephrine is triggered directly from the pituitary b. neurons carry a signal directly to the adrenal cortex c. axons stimulate the hypothalamus to release adrenalin d. neurons carry a signal directly from the hypothalamus to the adrenal medulla
The sympathetic postganglionic neurons release only norepinephrine while the adrenal medulla secretes mainly epinephrine (80%) and a small amount of norepinephrine (20%). The sympathetic postganglionic neurons do not secrete epinephrine because; Group of answer choices a. Epinephrine is not as widely used in the nervous system as norepinephrine b. Phenylethanolamine-N-methyltransferase (PNMT) which converts norepinephrine to epinephrine is present in the adrenal medulla, but not in sympathetic postganglionic adrenergic neurons c. Acetylcholine which stimulates the secretion of epinephrine does not act on postganglionic neurons d. Dopamine beta hydroxylase in hyperactive in the adrenal medulla

A scientist studying pain processing in a mouse model administers a drug that inhibits proteolytic processing of proopiomelanocortin (POMC) in the pituitary. An increased response to painful stimuli is noted in the treated animals compared to controls. The effect of the drug is due to a lack of effective levels of Group of answer choices β-endorphin ACTH Growth Hormone α-melanocyte-stimulating hormone (α-MSH)
Define the following terms: a. downregulation b. tropic hormone c. G protein-coupled receptor d. G protein e. cAMP
Elevated levels of cortisol have been shown to reduce areas of the hippocampus in the brain resulting in short term memory loss in older adults. (source: Sonia J. Lupien et al. Nature Neuroscience 1, 69-73 [1998]) Exposure to long-term stress results in elevated levels of cortisol in adults. Over time, cortisol may have detrimental effects on your health. Determine the effect below that is NOT a result of long-term stress. Select one: O a. Blood pressure is elevated. O b. The body is more prone to infections. c. The breathing rate increases. Od. Blood sugar levels are elevated. Clear my choice
