Endocrine Glands in the Cranial Cavity: Pineal & Pituitary

* Pineal gland: The pineal gland is a small, pea-sized gland located in the center of the brain. It produces melatonin, a hormone that helps regulate sleep-wake cycles.

* Pituitary gland: The pituitary gland is a small, bean-shaped gland located at the base of the brain. It is often called the "master gland" because it produces hormones that control many other endocrine glands.
