Hormones: Endocrine System

growth hormone releasing hormone (GHRH)

HYPOTHALAMUS, stimulates synthesis and release of growth hormone

thyrotrophin releasing hormone (TRH)

HYPOTHALAMUS, stimulates the pituitary gland to release thyroid-stimulating hormone (TSH)

corticotrophin releasing hormone (CRH)

HYPOTHALAMUS, stimulates the release of adrenocorticotropic hormone (ACTH) from the pituitary gland

somastatin

HYPOTHALAMUS, inhibits GH and TSH

dopamine

HYPOTHALAMUS, inhibits prolactin

oxytocin

HYPOTHALAMUS, uterine contractions

vasopressin

HYPOTHALAMUS, RELEASED IN PITUITARY, regulating fluid balance and blood pressure

adrenocorticotropic (ACTH)

PITUITARY GLAND, stimulates the adrenal glands to produce hormone

endorphins

PITUITARY GLAND, decreases feelings of pain

growth hormone

PITUITARY GLAND, stimulated by GHRH, stimulates growth of muscles and bones

thyroid stimulating hormone

PITUITARY GLAND

FSH and LH

PITUITARY GLAND, signals gonads to secrete hormones

Prolactin

POSTERIOR PITUITARY, stimulates milk production

oxytocin

POSTERIOR PITUITARY, uterine contractions, milk ejection

tri-iodothyronine, thyroxine

THYROID, regulates metabolism and crucial in development

calcitonin

THYROID, lowers blood calcium

pth

PARATHYROIDS, increases blood calcium

thymosin

develops T-cells for immune system
