Pineal and Pituitary Glands

The pineal gland is a small endocrine gland in the brain, situated beneath the back part of the corpus callosum, and secretes melatonin. The pituitary gland is located at the base of the brain that secretes hormones and regulates and controls other hormone-secreting glands and many body processes, including reproduction.
