The name 'master endocrine gland of body' is given to the pituitary gland. It is the major endocrine gland, a pea-sized body attached to the base of the brain that is important in controlling growth and development and the functioning of the other endocrine glands. The hormones of the pituitary gland help regulate the functions of other endocrine glands. The pituitary gland has two parts, the anterior lobe and posterior lobe. The hypothalamus sends signals to the pituitary to release or inhibit pituitary hormone production.
