The main gland of the endocrine system, the pituitary gland is considered
the “master” gland because the hormones it produces control
other glands as well as many body functions, including growth. The pituitary
includes the anterior and posterior pituitary.
The anterior pituitary affects growth, metabolism, electrolytes, blood
pressure, skin pigmentation, thyroid function and sexual development,
fertility and lactation. The posterior pituitary secretes oxytocin, a
hormone that increases uterine contractions and antidiuretic hormone (ADH),
which increases reabsorption of water by the kidney.
