The hypophysis or pituitary gland is called master gland. This is situated in a bony cavity called sella tursica below the hypothalamus and connected to the brain by a stalk.
:- This gland has two parts, the endodermal adenohypophysis and ectodermal neurohypophysis.
:- Adenohypophysis has three parts, pars distalis, pars tuberalis, and pars intermedia. Several tropic hormones are released from this part, like FSH, ACTH, GH, TSH, etc.
:- Neurohypophysis has three parts, pars nervosa, hypophysial stalk and median eminance. This is composed of blood vessels, pituicytes and nervous tissue. ADH and oxytocin are stored and released from this part.
Morphologically, there are three lobes, anterior lobe, middle lobe and posterior lobe.
