Solution:
Morphologically, pituitary consists of three regions - anterior lobe, middle (intermediate) lobe and posterior lobe. Anterior and middle lobes functionally constitute adenohypophysis while posterior lobe forms neurohypophysis. Major part of neurohypophysis is formed of pars nervosa. FSH and prolactin is secreted by anterior lobe of pituitary whereas MSH is secreted by riddle lobe. No hormones are synthesized in neurohypophysis, but two hormones - oxytocin and ADH, synthesized in the hypothalamus remain stored here, in very small vesicles called Herring bodies in the axons and terminals.
