The pituitary gland is situated under the brain and is an endocrine gland. The pituitary gland produces the adrenocorticotrophic hormones (ACTH), which are essential for all vital organs of the body. The pituitary gland is responsible for regulating the production of hormones in the adrenal and thyroid glands.
Hormones made by the pituitary gland include: 1  Prolactin hormone: causes a womanâs breasts to make milk after pregnancy. 2  Growth hormone: helps control body growth and the metabolism of sugar and fat. 3  Adrenocorticotropic hormone: causes the adrenal glands to make cortisol.
