Pituitary Anterior – Located in the base of the brain attached to the hypothalamus. Growth Hormone(GH) – Stimulates an increase in size and rate of division of body cells; enhances movement of amino acids through membranes; promotes growth of long bones. Prolactin (PRL) – Sustains milk production after birth; amplifies effect of LH in males. Thyroid-stimulating Hormone (TSH) – Controls secretion of hormones from the thyroid gland. Adrenocorticotropic Hormone (ACTH) – Controls secretion of certain hormones from the adrenal cortex. Follicle-stimulating hormone (FHS) – Development of egg-containing follicles in ovaries; stimulates follicular cells to secrete estrogen; in males, stimulates production of sperm cells. Luteinizing Hormone (LH) – Promotes secretion of sex hormones; release egg cell in females. Pituitary Posterior – Located in the base of the brain attached to the hypothalamus. Antidiuretic Hormone (ADH) – Causes kidneys to reduce water excretion; in high concentrations, raises blood pressure. Oxytocin (OT) – Contracts muscles in uterine wall and those associated with milk-secreting glands. Thyroid Gland – In front of trachea below larynx.

Thyroxine (T ) – Increases rate of energy release from carbohydrates; increases rate of protein synthesis; accelerates growth; stimulates activity in the nervous system. Triiodothyronine (T ) – Same as above, but five times more potent than thyroxine. Calcitonin – Lowers blood calcium and phosphate ion concentrations by inhibiting release of calcium and phosphate inos from bones and by increasing the rate at which calcium and phosphate ions are deposited in bones; increases excretion of calcium by the kidneys. Parathyroid – On back of thyroid.

Parathormone (PTH) – Increases blood calcium ion concentration and decreases phosphate ino concentration through actions in the bones, kidneys, and intestines. Adrenal Medulla – Inner top part of the kidney.

Epinephrine –
Norepinephrine –
Adrenal Cortex – Outer top of the...
