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
Glucagon
Pancreas
Increases BG levels by breaking down glucose
Liver and Skeletal Muscles
Insulin
Pancreas
Lowers BG by depositing glycogen
Liver and Skeletal Muscles
Melatonin
Pineal Gland
Reproductive Cycles & Body Rhythms
Brain
Thymus Hormone
Thymus
T-lymphocyte development and immune response
Acts locally
