-
hypothalmus
- releasing factors
- blood level drops hypothalmus reads the message & sends releasing factor to the pituitary, pituitary then sends stimulated amount of hormones to target gland
-
hypothalmus
- inhibiting factors
- blood level increase, hypothalmus reads the message and sends inhibiting factor to the pituitary; pituitary stops sending increased amount of hormones
-
oxytocin
- posterior pituitary gland
- causes contractions of uterus, release of milk
-
antidiuretic hormone (ADH)
- posterior pituitary gland
- stimulates kidneys to retain fluids & constrict blood vessels
-
growth hormone (GH)
- anterior pituitary gland
- increased rate of cell division that stimulates the bodies tissue growth
-
thyroid stimulating hormone (TSH)
- anterior pituitary gland
- stimulates thyroid to produce thyroid hormone
-
adrenal corticotropic hormone (ACTH)
- anterior pituitary gland
- stimulates secretion of cortisol from adrenal cortex
-
triiodothyronine (T3)
- thyroid gland
- increase metabolism & increase energy production
-
throxine (T4)
- thyroid gland
- increase metabolism & increase energy production
-
calcitonin
- thyroid gland
- decreases resorption of calcium phosphate from bones to blood
-
parathormone
- parathyroid gland
- increases resorption of calcium and phosphate from the bones to blood
-
epinephrine
- adrenal medulla
- increases heart rate and force of contraction (raises B/P)
-
norepinephrine
- adrenal medulla
- causes vasoconstriction in skin, viscera, skeletal muscles
-
adosterone
- adrenal cortex
- stimulates kidneys to retain sodium & excrete potassium
-
cortisol
- adrenal cortex
- increases blood glucose levels & decr inflammatory response
-
androgens
- andrenal cortex
- stimulates sex characteristics
-
glucagon
- pancreas
- increases conversion of glycogen to glucose in the liver
-
insulin
- pancreas
- increases conversion of excess glucose to glycogen
-
hypothalmus (communication center)
