-"Uterine responses depend on stages of menstrual cycle, amount of circulating estrogen and progesterone, and other factors. kPalms of hands and some other sites ("adrenergic sweating").
lThere is significant variation among species in the receptor types that mediate certain metabolic responses. All three b adrenergic receptors have been found in human fat cells. Activation of adrenergic receptors produces a vigorous thermogenic response as well as lipolysis. The significance is unclear. Activation of b adrenergic receptors also inhibits leptin release from adipose tissue. ADH, antidiuretic hormone, arginine vasopressin; AV, atrioventricular; AP, action potential.
