Question

The endocrine system relies on the hypothalamus to do which of the following?a) activate the pituitary gland;b) release hormones into the bloodstream;c) stimulate the adrenal glands;d) regulate heart rate and respiration.

Answer 1

The hypothalamus, besides controlling water balance, appetite, sleep, blood pressure and temperature, also secretes hormones to stimulate or supress the releasing of hormones by the pituitary gland. That means that the hypothalamus regulates if the pituitary gland is active or not. Therefore, the correct answer is a) activate the pituitary gland.
