Main Image: The Pituitary gland is a pea-sized endocrine (hormone-producing) gland weighing about 0.5 g situated at the bottom of the skull sandwiched between the optic nerves, in humans. The pituitary gland secretes hormones. Hormones are chemicals that travel through the blood stream.
The pituitary gland is a tiny organ, the size of a pea, found at the base of the brain. As the âmaster glandâ of the body, it produces many hormones that travel throughout the body, directing certain processes or stimulating other glands to produce other hormones. The pituitary gland makes or stores many different hormones. The following hormones are made in the anterior (front part) of the pituitary gland: 1  Prolactin - stimulates breast milk production after childbirth. 2  Growth hormone (GH) - stimulates growth in childhood and is important for maintaining a healthy body composition and well-being in adults.
