Endocrine System. Flashcards
Antidiuretic hormone.
Reduces urinary excretion of water (pituitary)
Oxytocin
(pituitary) Stimulates contraction of the smooth muscles of uterus and intestines
Fsh & lh
(pituitary) Stimulates gonads to secret sex hormones.
Thyroid stimulating hormone.
(pituitary) Stimulates thyroid gland to secrete hormones.
Adrenocorticotropin hormone
(pituitary) Stimulates adrenal glands to secrete glucocorticoids.
Growth hormone.
(pituitary) Stimulates general growth and skeletal growth &a promotes metabolic functions.
Prolactin
(pituitary) Initiates and maintains breastmilk secretion in female.
Thyroxine and triiodothyronine
(Thyroid) Increase oxygen consumption and heat production and affects many metabolic functions.
Calcitonin
(Thyroid) Decreases blood calcium and phosphate levels.
Parathyroid hormone
(Parathyroids) Raises plasma calcium levels and lowers plasma phosphate levels.
Epinephrine
Affects carbohydrate metabolism, generally promoting hyperglycemia. Constructs blood vessels in the skin, mucous membranes, and kidneys- but dilates vessels in the skeletal muscle.
Norepinephrine
(Adrenals) Increases heart rate and force of contraction of the myocardium and constricts blood vessels in most areas of the body.
Mineralocorticoids (aldosterone)
(Adrenals) Promote transcription of sodium and excretion of potassium in the kidneys.
Glucocorticoids (cortisol)
(Adrenals) Promote protein and triglyceride breakdown.
Insulin
(Pancrease) causes liver and muscle cells to take up glucose and store it in the form of glycogen. Encourages fat cells to take on blood lipids and turn them into triglycerides. Also has several other anaerobic effects throughout the body.
