A two-lobed, pea-size gland at the base of the brain and attached to the hypothalamus that controls the endocrine system. The major divisions of the gland are the anterior lobe, or adenohypophysis, and the posterior lobe, the neurohypophysis. Each lobe produces hormones. The anterior lobe produces growth hormone, thyroid-stimulating hormone, adrenocorticotropic hormone, prolactin, luteinizing hormone (LH), and follicle-stimulating hormone (FSH), the last two called gonadotropins because they stimulate the gonads. The posterior lobe releases anti-diuretic hormone (vasopressin) and oxytocin. These hormones regulate many body functions from growth to birth contractions.
