What structures in the nipple and areola cause the nipple to become erect and help in the discharge of milk? - Answer Rings of smooth muscle are located in the areola and nipple areas of the breast. When this muscle tissue constricts, the nipple becomes erect, and during lactation, this results in the discharge of milk. This region has an abundance of nerve endings, which are in close approximation to the arterioles that supply blood to the nipple and areola. Stimulation of the nipple by tempera...
