INTRODUCTION:-
The pituitary gland is located in a Bony cavity called sella tursica and is attached to thalamus by a stalk.It is divided anatomically into an adenohypophysis and neurophysis.

Adenohypophysis consists of two portions ,pars distalis and para intermedia.

The pars distalis region of pituitary, commonly called anterior pituitary produces , growth hormone (GH) , Prolactin (PRL) , thyroid stimulating hormone (TSH),
adrenocorticotrophic hormone (ACTH) , luteinizing hormone (LH) and follicle stimulating hormone (FSH).

Pars intermedia secrets only one hormone called melanocyte stimulating hormone (MSH).

Neurohypophysis also known as posterior pituitary, stores and release two hormones called oxytocin and vasopressin ,which are actually synthesized by the hypothalamus and are transported axonally to neurohypophysis.
