Hormones Flashcards
Thyroid Stimulating Hormone (TSH)
Anterior Pituitary
Stimulates normal development and secretory activities of thyroid gland
Thyroid Gland
Human Growth Hormone (HGH)
Anterior Pituitary;
Increase body growth by increasing protein synthesis; fat metabolism; glucose conservation
Bones and Skeletal Muscles
Adrenocorticotropic (ACTH)
Anterior Pituitary
Stimulates adrenal cortex to release corticosteroid hormones that help the body resist stressors
Adrenal Cortex
LH
Anterior Pituitary
Females: Triggers ovulation; promotes ovarian hormones
Males: Stimulates interstitial cells of testes to produce testosterone
Gonads
*Gonadotropin
FSH
Anterior Pituitary
Females: w/LH, promotes egg containing ovarian follicle to mature
Both: Stimulates gamete production
Gonads
*Gonadotropin
Prolactin
Anterior Pituitary
Stimulates milk production in the breasts
Mammary Glands
Oxytocin
Posterior Pituitary
Stimulates uterine contractions; initiates labor; initiates milk ejection from breasts
Uterus
ADH/Vasopressin
Posterior Pituitary
Stimulates kidney tubule cells to reabsorb water
Kidneys
T3 and T4 (Triiodothyronine and Thyroxine)
Thyroid
Stimulates enzymes concerned with glucose oxidation (increases metabolic rate, oxygen consumption, & body heat); maintains BP; regulates tissue growth and development
Every cell in body EXCEPT brain, gonads, & thyroid
Calcitonin (CT)
Thyroid
Inhibits osteoclasts activity; stimulates uptake of calcium into the bone matrix
Bones
Parathyroid Hormone (PTH)
Parathyroid
Increases calcium in blood by increasing osteoclasts action; enhances reabsorption of Ca in kidneys; excretes phosphates from kidneys; absorption of Ca by intestinal mucosal cells
Bones, Kidneys, & Intestines
Cortisol
Adrenal Cortex
Provokes formation of glucose from non carbohydrate molecules like fats and proteins
Total Body
Aldosterone
Adrenal Cortex
Increases BL’s Na+; Decreases BL’s K+; BV and BP increases
Distal parts of Kidney tubules
Testosterone (weak androgen)
Adrenal Cortex
Onset of puberty; makes you hairy
Gonads
Epinephrine/Norepinephrine
Adrenal Medulla
“Fight or Flight” responses; resist stress
Total Body
