Anatomy of the pituitary gland:
The pituitary gland is sometimes called the "master" gland of the endocrine system, because it controls the functions of the other endocrine glands. The pituitary gland is no larger than a pea, located at the base of the brain. The gland is attached to the hypothalamus (a part of the brain that affects the pituitary gland) by nerve fibers. The pituitary gland itself consists of three sections:
the anterior lobe
the intermediate lobe
the posterior lobe
Functions of the pituitary gland:
Each lobe of the pituitary gland produces certain hormones.
