Chap 10 Endocrine System-Hormones
| Question | Answer |
|---|---|
| -anterior pituitary -stimulates growth in all organs | Growth Hormone (GH) |
| -anterior pituitary -stimulates breast development during pregnancy & milk secretion after delivery | Prolactin (PL) |
| -anterior pituitary -stimulates secretion of adrenal cortex hormones (cortisol) | Adrenocorticotropic hormone ( ACTH) |
| -anterior pituitary -stimulates secretion of thyroid hormones | Thyroid-stimulating hormone (TSH) |
| -anterior pituitary -female:estrogen secretion & follicle maturity & ovulation;causes luteinization of ruptured follicle;development of corpus luteum male:stimulates testes to secrete testostrone | luteinizing hormone (LH) |
| -anterior pituitary -female:stimulates development of ovarian follicles & secretion of estrogens male:stimulates seminiferous tubules of testes to grow & produce sperm | follicle-stimulating hormone (FSH) |
| -posterior pituitary -stimulates uterine contractions at the end of pregnancy; stimulates the the release of milk into the breast ducts | oxytocin |
| -posterior pituitary -stimulates retention of water by kidneys | anti-diuretic hormone (ADH) |
| -thyroid -stimulates the energy metabolism of all cells | thyroxine ( T4) |
| -thyroid -stimulates the energy metabolism of all cells | triiodothyronine ( T3) |
| -thyroid -inhibits the breakdown of bone;causes a decrease in blood calcium concentration | calcitonin |
| -parathyroid -stimulates the breakdown of bone; causes an increase in blood calcium concentration | parathyroid hormone ( PTH) |
| -adrenal cortex ( middle layer) -stimulates gluconeogenesis causing an increase in blood glucose concentration; also have antiinflammatory & antiimmunity, antiallergy effect | glucocorticoids (cortisol ) |
| -adrenal cortex (outer layer) -regulate electrolyte & fluid homeostasis; increases sodium; decreases potassium | mineralcorticoids ( aldosterone ) |
| -adrenal cortex ( inner layer) -stimulates sex drive in females but have negligible effects in the male | sex hormones ( Androgens ) |
| -adrenal medulla -prolong & intensify the sympathetic nervouse response during stress increases blood glucose & Heartrate | epinephrine ( adrenaline) & norepinephrine |
| -pancreas ( Beta cells ) -promotes glucose entray into all cells causing a decrease in blood glucose concentration | insulin |
| -pancreas (Aplha cells ) -stimulates liver glycogenolysis causing an increase in blood glucose concentration | glucagon |
| -ovary -promotes development & maintenance of female breast and menstrual cycle | estrogen |
| -testes -promotes development & maintenance of male sex characteristics | testosterone |
| -thymus -promotes development of immune system cells | thymosin |
| -pineal gland -third eye;involved in body's internal clock & sleep cycle responsive to light | melatonin |
