Definition
Hypophyseal refers to the hypophysis, which is another name for the pituitary gland. The pituitary gland is a small, pea-sized gland located at the base of the brain. It's the 'master gland' because it controls many other endocrine glands in the body. It secretes hormones that regulate growth, metabolism, and reproduction. Therefore, hypophyseal relates to the pituitary gland and its functions.
