Flashcards in Chapter 75 - Guyton Deck (22):
ACTH, TSH, FSH, LH, PRL, GH
Tells the pituitary to make hormones!
stimulates production of thyroid hormones
stimulates postnatal body growth, secretion of IGF-1, stimulates triglyceride lipolysis, inhibits action of insulin on carbohydrate and lipid metabolism
causes ovulation and formation of corpus luteum in the ovary, stimulates production of estrogen and progesterone in ovary, stimulates testosterone production in testis
stimulates development of ovarian follicles, regulates spermatogenesis in testis
stimulates production of glucocorticoids and androgens by the adrenal cortex, maintains size of zona fasciculata and zona reticularis of cortex
TRH, GnRH, CRH, GHRH, somatostatin, PIH
Two areas that the anterior pituitary hormones can be regulated.
hypothalamus and anterior pituitary
Biological actions of GH.
decrease adiposity, increase LBM, increase protein synthesis, increase organ function, increase chondrocyte function (bone health)
Most important factor determining GH secretion.
Metabolic effects of GH.
increase plasma glucose, free fatty acids, ketoacids, and decrease plasma amino acids
Hormones that will facilitate HSL-mediated breakdown of triglycerides in adipose tissue for energy.
GH, cortisol, T3, EPI
Hormone that will inhibit HSL-mediated breakdown of triglycerides in adipose tissue for energy.
insulin (also facilitates formation of triglycerides from glucose)
T/F Somatostatin inhibits GH release.
Stimulates GH release.
sleep, exercise, calorie deprivation, fasting, puberty, androgens and estrogens
Abnormalities of GH secretion.
gigantism, acromegaly, dwarfism
