14 terms
Terms | Definitions |
|---|---|
 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 |
| Oxytocin | stimulates contractions of uterus during labor stimulates contraction of mammary gland alveoli (milk ejection); rises in ejaculation (not sure why) |
| Mineralocorticoids | stimulate kidneys to retain Na+ and water, and excrete K+ |
| Glucocorticoids | stimulate gluconeogenesis; inhibit glucose utilization (increase blood glucose); promote lipolysis; exogenous corticosteriods are anti-inflammatory and immuno suppressive |
| Androgens | 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 |
| calcitonin | 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 |
