The pituitary gland is small and oval-shaped. It’s located behind your nose, near the underside of your brain. It’s attached to the hypothalamus by a stalklike structure. The hypothalamus is a small area of your brain.
The posterior lobe of the pituitary gland also secretes hormones. These hormones are usually produced in your hypothalamus and stored in the posterior lobe until they’re released. Hormones stored in the posterior lobe include: Vasopressin. This is also called antidiuretic hormone.
Located at the base of the brain, the pituitary gland is protected by a bony structure called the sella turcica of the sphenoid bone. Median sagittal through the hypophysis of an adult monkey.
