Somatostatin
release - hypothalamus
target- pituitary gland and pancreas
action - Inhibits secretion of GH and TSH
FSH
follicle-stimulating hormone
release - anterior pituitary
target- gonads (ovaries and testies)
action - sperm production, ovaries follicle production, production of sex hormones
LH
Luteinizing hormone
release - anterior pituitary
target- gonads ( ovaries and testies)
action - Stimulates ovulation, corpus luteum to secrete progesterone, testes to secrete testosterone

action -stimulate adrenal cortex to release glucocorticoids
prl
prolactin
release - anterior pituitary
target- Mammary gland
action - stimulated mamilary gland to synthesize milk, increase testosterone secreation

action - stimulates mitosis and cellular differentiation
ADH
antidireutic hormone
release - posterior pituitray
target - Kidney tubules, smooth muscle in arterioles
action -Increases water retention; reduces urine volume and prevents dehydration
OT
oxytocin
release - posterior pituitary
target -Uterine smooth muscle, mammary gland

release - pineal gland
target - brain tissue
action -Circadian rhythms, inverse relationship to light
Thymopoietin
release- thymus
target- T-lymphocyte cells in blood and lymphatic organs
action -stimulate development of lymphatic organs and activate T-cells
Thymosin
release- thymus
target- T-lymphocyte cells in blood and lymphatic organs
action -stimulate development of lymphatic organs and activate T-cells
Thymulin
release- thymus
target- T-lymphocyte cells in blood and lymphatic organs
action -stimulate development of lymphatic organs and activate T-cells
Thyroxine
release - thyroid
target - most tissues
action - Increases metabolic rate, O2 consumption, heat production (calorigenic effect), appetite, GH secretion, alertness, reflexes
Triiodothyronine
release - thryoid
target - most tissues
action - Increases metabolic rate, O2 consumption, heat production (calorigenic effect), appetite, GH secretion, alertness, reflexes
Calcitonin
release - thryoid
target - bone
action -Stimulates osteoblast activity, lowers blood calcium levels
pth
parathyroid hormone
release - parathyroid gland
target - bone and kidneys
action - Increases blood Calcium levels, promotes synthesis of calcitriol, increases absorption of Calcium, decreases urinary excretion, increases bone resorption (osteoclast activity)
Cortisol
release - adrenal cortex
target - may tissues
action -(Stress hormone), stimulates fat and protein catabolism, gluconeogenesis, release of fatty acids and glucose into blood
Aldosterone
release-adrenal cortex
target - kidneys
actions -Stimulates Na retention and K excretion (helps maintain BP), water retained with Na by osmosis, so blood volume and BP maintained
