Physiology Exam 3

Growth Hormone (GH)
promotes movement of amino acids into cell (promotes growth)
Thyroid stimulating hormone (TSH)
stimulates thyroid gland to produce T4 and T3
adrenocorticotropic hormone (ACTH)
corticotropin; stimulates adrenal cortex to secrete glucocorticoids (cortisol)
Follicle Stimulating hormone (FSH)
folliculotropin; stimulates ovarian follicles/sperm cell production and perhaps other systems as well
Luteinizing hormone (LH)
luteotropin; stimulates ovulation and CL formation; interstitial cell stimulating hormone (ICSH) in males; secretion of male sex hormones from interstitial cells
Prolactin (PRL)
stimulation of milk production supporting role in regulation of male reproductive system; acts on kidneys to help regulate water and electrolyte balance
Anti-Diuretic hormone (ADH)
vasopressin; promotes reabsorption (retention) of water in kidney
stimulates contractions of uterus during labor stimulates contraction of mammary gland alveoli (milk ejection); rises in ejaculation (not sure why)
stimulate kidneys to retain Na+ and water, and excrete K+
stimulate gluconeogenesis; inhibit glucose utilization (increase blood glucose); promote lipolysis; exogenous corticosteriods are anti-inflammatory and immuno suppressive
male sex steriods secreted by gonads; some produced by body but high doses are illegal in sports
thyroid follicles
contain colloid (protein rich fluid) - accumulates iodine
from parafollicular cells; antagonistic to PTH (lowers blood Ca+); ihibits dissolution of bone crystals; stimulates Ca+ excretion in urine; 25 hour half life
Parathyroid hormone (PTH)
most important in blood calcium regulation; raises blood Ca+ by acting on bones, kidneys, and intestine
