Thyroid gland: Triiodothyronine (T3) promote growth and maturation of tissues
Thyroid gland: Calcitonin, in bone, decreases bone resorption Net effect: decreases blood calcium levels; antagonistic to PTH
Parathyroid Gland a small, pea-sized glands, located in the neck, hormones maintain the balance and phosphate in the body
Parathyroid Gland: Parathyroid hormone (PTH), in bone, promotes osteoclastic activity
Parathyroid Gland: Parathyroid hormone (PTH), in intestines, increases calcium absorption
Parathyroid Gland: Parathyroid hormone (PTH), in kidney, Increases calcium
reabsorption
Adrenal Glands or Suprarenal gland, produces hormones that help the body respond to stress, regulate blood pressure, and maintain electrolyte balance.
Adrenal cortex: Mineralocorticoids Aldosterone, in kidney, increases sodium
reabsorption and potassium excretion, and promotes water retention
Adrenal cortex: Glucocorticoids Cortisol, in liver, fat, skeletal muscle, most tissues, increases fat and protein breakdown in favor of glucose synthesis, and decreases inflammatory response
Adrenal cortex: Androgens, stimulate sex drive in females, and stimulate hair growth
Adrenal medulla: Androgens, epinephrine and norepinephrine, stimulate the sympathetic response, “fight or flight”
Pancreas produces digestive enzymes and regulates blood sugar levels through hormone secretion
Pancreas: Insulin, in liver, stimulates glycogen synthesis from glucose and
amino acids. Net effect: decrease blood glucose levels
Pancreas: Glucagon, in liver, increases breakdown of glycogen, Net effect: increase blood glucose levels;
Thymus gland plays an important role in the development and maturation of T lymphocytes
Thymus gland: Thymosine, in immune tissues, promotes immune system
maturation
Pineal body produces hormone which regulates the sleep-wake cycle
Pineal body: Melatonin, in hypothalamus, inhibits the production of gonadotrophic releasing hormones
Testes produces sperm cells and the hormone testosterone.
Testes: Testosterone,in seminiferous tubule, promotes sperm maturation, promotes development of primary and secondary male sexual characteristics
Ovaries play a central role in the production of the egg cell and hormones that regulate the menstrual cycle and pregnancy
Ovaries: Estrogen and Progesterone, in female reproductive tract, regulate the menstrual cycle, promote the development of primary and secondary
female sexual characteristics
Hypothalamus produces hormones that stimulate or inhibit the release of hormones from the pituitary gland.
