by a dural fold (diaphragma sellae). The pituitary is functionally connected to the hypothalamus by the median eminence via a small tube called the infundibular stem (Pituitary stalk). The pituitary fossa‚ in which the pituitary gland sits‚ is situated in the sphenoid bone in the middle cranial fossa at the base of the brain. The pituitary gland secretes nine hormones that regulate homeostasis. Contents [hide] * 1 Anatomy * 2 Embryology * 2.1 Anterior * 2.2 Posterior * 2.3 Intermediate
