why pituitary gland in known as master 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, and is located at the base of the brain. The gland is attached to the hypothalumus (a part of the brain that affects the pituitary gland) by nerve fibers. http://www.umm.edu/endocrin/pitgland.htm…
