What is the function of the GH?
Promotes growth of all body tissues
What is the function of TSH?
stimulates the thyroid gland to produce thyroid hormones such as thyroxine
What is the function of ACTH (adrenocorticotropic hormone)?
stimulates adrenal cortex to produce cortical hormones such as cortisole and aldosterone
What is the function of prolactin?
stimulates the secretion of milk by the mammary glands
What is the function of LH?
development of corpus luteum at the rupture site of the ovarian follicle in females OR stimulates secretion of testosterone in males

posterior lobe of pituitary
What is the function of thyroxine?
- influences physical and mental activities
- increaess metabolic rate required for normal growth
What is the function of calcitonin?
LOWER calcium leven in blood! Takes from blood and stores it in bones
What is the function of PTH?
Increase blood Ca level! Takes from bone to blood

- Diet: regular
- Meds/Nursing: verbalize feelings; observe for s/s of DM; surgery (observe for transiet diabetes insipidus)
What disorder is caused by decreased ADH?
- Diabetes Insipidus
- S/s: greater urinary output; low specific gravity of urine; hypovolemia; increased thirst; output will not be less than intake
- Diet: regular but increase fluids
- Meds/Nursing: monitor hydration status; I&O; check specific gravity of urine
