HOSA Pathophysiology Endocrine
hyperpituitarism - Excessive secretion of one or multiple hormones (often GH). Disorders and symptoms
dependant on hormones affected
gigantism - Abnormal overgrowth of the entire body that is caused by excessive secretion of the growth
hormone before puberty
acromegaly - hypersecretion of GH after puberty
hypopituitarism - condition of diminished hormone secretion from the anterior pituitary gland
Growth hormone - promotes bone/tissue gorwth
Thyrotropin (TSH) - stimulates thyroid gland and production of thyroxine
ACTH (corticotropin - stimulates adrenal cortex to produce glucocorticoids
FSH Follicle-stimulating - initiates growth of over; spermatogenesis in testes
Luteinizing LH - causes ovulation;stimulates ovaries to produce estrogen and progesterone;stimulates
testosterone development
Prolacitn - breast development and formation of milk
MSH - stimulates skin pigmentation
Vsopressin ADH - water reabsorbtion by renal tubules
Oxytocin - uterine contractions; ejection of milk;
