The pituitary gland is a small gland placed in the center of the skull, beneath the hypothalamus and behind the bridge of the nose. It is connected to the hypothalamus by nervous tissue called the infundibulum.
In the limbic system, the pituitary works in sync with the thalamus and the hypothalamus to produce various hormones. As a result, these hormones affect growth, metabolism, sexual development and human reproduction.
The pituitary gland oversees the entire endocrine system, and, as such, is known as the master endocrine gland.
As the master of the endocrine system, the pituitary monitors and instructs the other hormones and glands in the body. So, the pituitary can speak to the rest of the endocrine system, and the glands of the system also can speak back to the pituitary.
