Answer Key / Explanation : (a) -

(a)

The nuerohypophysis or posterior lobe of pituitary gland secretes two hormones,  oxytocin or pitosin and vasopressin or pitressin or antidiuretic hormone (ADH). Oxytocin is also called as birth hormone or milk ejecting hormone because it promotes contraction of the uterine muscles and myoepithelial cells of the lactating breast and helps in squeezing milk into the large ducts behind the nipple. ADH increases the reabsorption of water in the distal convoluted tubule, collecting tubules and collecting ducts.
