GENERAL INFORMATION

• It is divisible into two distinct portions, the anterior pituitary or adenohypophysis and posterior pituitary or neurohypop­hysis or pars nervosa.
• The pituitary is connected to the brain by means of the pituitary stalk.
• The adenohypophysis consists of three portions, viz., the pars distalis, pars tuberalis and the pars intermedia.
• The pars distalis is the largest of the three parts and secrets the tropic hormones.
• The pars tuberalis does not have any endocrine function.
• The pars intermedia produce melanocyte-stimulating hormone (MSH) and regulate the pigmentation in the body.
