Question | Answer |
---|---|
What is the target/function of melatonin? | BRAIN; Helps set biological clock |
What is the target/function of releasing hormones? (RH) | ANTERIOR LOBE; Regulates secretion of anterior pituitary hormones: stimulates secretion |
What is the target/function of inhibiting hormones? (IH) | ANTERIOR LOBE; Regulates secretion of anterior pituitary hormones: inhibits secretion |
What is the target/function of ACTH? | ADRENAL CORTEX; Stimulates secretion of cortisol and androgens and to a lesser extent aldosterone |
What is the target/function of FSH? | OVARIES/TESTES; In female: stimulates egg growth and estrogen secretion In male: stimulates sperm production |
What is the target/function of LH? | OVARIES/TESTES; In female: triggers ovulation and estrogen and progesterone secretion In male: stimulates testosterone secretion |
What is the target/function of hGH? | BONE/CARTILAGE CELLS, SKELETAL MUSCLE, OTHER BODY TISSUES; Stimulates tissue growth and metabolism |
What is the target/function of TSH? | THYROID GLAND; Stimulates growth of thyroid gland and T3 & T4 secretions |
What is the target/function of PRL? | MAMMARY GLANDS; Stimulates milk production (lactation) |
What is the target/function of ADH? | KIDNEYS; Decreases water loss in urine and returns it to the blood |
What is the target/function of OT? | UTERUS/MAMMARY GLANDS; Stimulates uterine contraction in childbirth and milk ejection during breast feeding |
What is the target/function of thyroxine (T4) & (T3)? | MOST BODY CELLS; Increases cellular metabolism and BMR |
What is the target/function of PTH? | OSTEOCLASTS/BONES, KIDNEYS, SMALL INTESTINE; Increases blood calcium levels |
What is the target/function of androgens? | INCREASES FEMALE SEX DRIVE; in female: body cells involved in secondary sex characteristics |
What is the target/function of epinephrine and norepinephrine? | BODY CELLS INVOLVED IN FIGHT/FLIGHT RESPONSE (SYMPATHETIC NS); Promotes fight-or-flight response |
What is the target/function of aldosterone? | KIDNEYS; Decreases water & sodium loss in urine & returns them to the blood, but increases potassium urine loss |
What is the target/function of cortisol? | LIVER, MUSCLE AND CELLS INVOLVED IN BODY DEFENSES; Increases resistance to stress, increases blood glucose levels, & decreases internal inflammation |
What is the target/function of insulin? | MOST BODY CELLS; Promotes blood glucose uptake by most body cells, esp muscle and fat cells |
What is the target/function of glucagon? | LIVER; Increases blood glucose levels by stimulating the breakdown of glycogen |
What is the target/function of testosterone? | TESTES, MUSCLE, & OTHER BODY CELLS INVOLVED IN MALE SEXUAL CHARACTERISTICS; Stimulates development of male sex characteristics, male sex drive, & regulates sperm production |
What is the target/function of estrogens? | UTERUS, MAMMARY GLANDS & OTHER BODY CELLS INVOLVED IN FEMALE SEXUAL CHARACTERISTICS; Stimulates development of female sex characteristics, & helps regulate menstrual cycle |
What is the target/function of progesterone? | UTERUS/MAMMARY GLANDS; With estrogen promotes breast development and cyclic changes in the uterus during menstrual cycle |
What hormones are secreted by the pineal gland? | Melatonin |
What hormones are released by the hypothalamus? | Releasing hormones (RH) Inhibiting hormones (IH) ADH (posterior lobe) OT (posterior lobe) |
What hormones are released by the anterior lobe? | ACTH FSH LH hGH TSH PRL |
What hormones are released by the thyroid gland? | Thyroxine (T3,T4) |
What hormones are released by the parathyroid gland? | PTH |
What hormones are released by the adrenal cortex? | Androgens Aldosterone Cortisol |
What hormones are released by the adrenal medulla? | Epinephrine Norepinephrine |
What hormones are released by the pancreas? | Insulin |
What hormones are released by the testes? | Testosterone |
What hormones are released by the ovaries? | Progesterone |
What is a tropic hormone? Give an example. | Hormones that control the release of other hormones. Releasing hormones. |
