Exam 19: Endocrine Glands

The vascular link between the hypothalamus and the adenohypophysis is termed the hepatic portal system.

The principal thyroid hormone is:

The corticotroph cells of the adenohypophysis secrete growth hormone.

Which hormones are produced by the hypothalamus to control the adenohypophysis?

Hormones of the neurohypophysis are actually made by cells of the supraoptic or sella turcica nuclei.

An abnormally high metabolic rate could be associated with the functioning of the:

Insulin lowers blood concentrations of glucose.

The pituitary is attached to the hypothalamus by a stalk termed the pars intermedia.

Most hormones released by the hypothalamus enter the hypophyseal portal system.

Secretion of _____ is controlled mainly by the renin-angiotensin mechanism and blood potassium concentration.

Specific chemical-releasing factors made in the adenohypophysis are responsible for the release of antidiuretic hormone and oxytocin into the blood.

Besides the cells of the kidney,target cells of ADH include muscle cells of the walls of the arteries.

The anterior pituitary develops from the downward projection of the brain.

Prolactin affects:

Glucocorticoids stimulate the conversion of protein to sugar.

Parathyroid hormone causes the kidney to retain calcium and excrete phosphate.

Match each hormone with its corresponding description. -stimulates testosterone production in males

When the amount of antidiuretic hormone increases,the body tries to get rid of excess fluid and the volume of urine increases.

Which of the following statements is not true of the pineal gland?

Briefly summarize how growth hormone affects metabolism.
