The central nervous system stimulates hypothalamus-releasing factor,
k k k k k k k k k k k k k k




which acts on the anterior pituitary gland to secrete thyroid-stimulating
k k k k k k k k k k




hormone (TSH) and stimulates the release of thyroxine (T4) and
k k k k k k k k k k




triiodothyronine (T3).

The central nervous system directly stimulates the release of insulin,
k k k k k k k k k k k k k k k k k




which reduces blood glucose levels.

The central nervous system directly stimulates the adrenal medulla to
k k k k k k k k k k k k k k k k k




secrete epinephrine and stimulates hypothalamus-releasing factor, which acts

on the anterior pituitary gland to secrete adrenocorticotropic-stimulating

hormone (ACTH), stimulating the release of cortisol.

The central nervous system stimulates the hypothalamus to synthesize
k k k k k k k k k k k k k k k k




oxytocin and antidiuretic hormone, which are secreted by the posterior

pituitary, activating uterine contraction and renal absorption of water.
