PITUITARY GLAND (Hypophysis Cerebri)

Location:

Pituitary fossa in the sella turcica of the sphenoid bone saddled between the middle and posterior clinoid processes. Pituitary stalk penetrates the diaphragma sella. Sella is lined with dura. Regulated by the hypothalamus (releasing or inhibiting hormones).

Divisions:

1. Neurohypophysis (downgrowth of diencephalon):

Secretes ADH (vasopressin) and oxytocin.

2. Adenohypophysis (consists of pars anterior, intermedia and tuberalis).

Secretes tropic hormones (GH, ACTH, TSH, FSH, LH, prolactin). Releasing hormones or factors of hypothalamus control pituitary function (ie CRF, TRF, GHRF, FSHRF, LRF).

Blood Supply:

Internal carotid artery branches (hypophysial artery); portal vessel. The pituitary portal system is an intricate venous network and channels connecting the hypothalamus and anterior pituitary gland.

Embryology:

Ectoderm origin.

1. Anterior lobe: from Rathke's pouch (stomodeum).

2. Posterior lobe: diencephalon, neuro-ectoderm diverticulum.
