Clinical Concept

Pituitary Gland

The 'master gland' at the base of the brain that secretes growth hormone, ACTH, TSH and other downstream hormones.

Definition

The pituitary is a pea-sized gland at the base of the hypothalamus that coordinates endocrine output. Its anterior lobe secretes growth hormone, adrenocorticotropic hormone (ACTH), thyroid-stimulating hormone (TSH), prolactin and the gonadotropins; its posterior lobe releases oxytocin and vasopressin. GHRH analogs and GH secretagogues act at the anterior lobe's somatotroph cells.
