Histological studies revealed that the mammary gland nipple have smooth muscle fibres along the nipple channel. These fibres infiltrate the connective tissue parallel to the skin. The ring muscles are not obvious. Delays in the milk excretion in mice may be due to specifics of allocation and functioning of the nipple smooth muscles. To obtain milk, a mechanical action upon the nipple and a synchronised release of oxitocin into the blood are necessary.
