Oxytocin hormone is secreted from the posterior lobe of pituitary gland. It promotes contraction of the uterine muscle and myoepithelial cells of lactating breast, squeezing milk into the large ducts behind the nipple. Because of its role oxytocin is called birth hormone.
The anterior lobe of pituitary gland secretes a somatotropic hormone, thyroid stimulating hormone, adrenocorticotropic hormone and gonadotropic hormones.
The prolactin hormone or luteotropic hormone is secreted from the anterior lobe of pituitary gland. It activates the growth of breasts during pregnant and secretion of mammary glands after childbirth.
