Pituitary gland: A gland found at the base of brain behind the sinuses.

Pineal gland: A gland found near the center of the brain that may be linked to sleep patterns.

Parathyroid: Four tiny glands in the neck that play a role in bone development.

Islet cells in the pancreas: Cells in the pancreas control the release of the hormones insulin and glucagon.

Ovaries: The female reproductive organs that release eggs and produce sex hormones.
