1. CORTICOTROPIN & POSTPRANDIAL PRESENTATIONBy: Frank LemondBiology 1207/17/10 2. CORTICOTROPINWhat = corticotropin?The adrenal glands, aka the suprarenal glands, are small triangular glands located on top of each kidney.An adrenal gland has 2 parts: the outer region = known as the adrenal cortex & the inner region = called the adrenal medulla.Both parts of the adrenal glands, the cortex & medulla, perform different jobs. 3. CORTICOTROPIN (continued)The adrenal glands work with the pituitary gland & the hypothalamus in the following ways:1.the hypothalamus makes corticotropin-releasing hormones, which stimulate the pituitary gland.2.the pituitary gland, in turn, makes corticotropin hormones, which stimulate the adrenal glands to make corticosteroid hormones. 4. II.POSTPRANDIALPOSTPRANDIAL literally means after eating a meal.This = opposed to preprandial (before a meal).This word = sometimes used in relationship to blood sugar (glucose) levels, usually measured 2 hours before & after eating in a postprandial sugar test.The American Diabetes Assn. recommends a postprandial sugar level under 180 mg/dl & a preprandial plasma sugar between 90-130 mg/dl.This = not, however, the only context in which this word = used. 5. II.POSTPRANDIAL (continued)Postprandial hyperglycemia = high blood sugar after a meal.It can be checked in a postprandial sugar test.Postprandial dip = a mild decrease in blood sugar after eating a large meal, possibly leading to sleepiness.Postprandial hypotension = a drastic decline in blood pressure which occurs after eating. 6. II.POSTPRANDIAL(continued)Postprandial regurgitation = a unique symptom of rumination syndrome.Postprandial thermogenesis = heat production due to metabolism after a meal, temporarily increasing the basal metabolic rate.
