The nipple contracts the organization and the smooth muscle by the compact knot is composed. The smooth muscle assumes the circumduction or the radiated arrangement, when has the machinery stimulates, the smooth muscle contracts, may cause the nipple erection, among them and extrudes the drive pipe and the lactic sinus discharges tolerant. The areola department skin has the hair and the gland. The gland has the sweat gland, the sebaceous glands and the mammary gland. His/her sebaceous glands call the glandulae areolares, but shows greatly shallowly, the secretion has protects the skin, to lubricate the nipple and the baby lips’ function.

??Mammary gland located at between hypodermic shallow fascia shallow layer and in-depth. The shallow fascia extends to the mammary gland organization in forms the septum interlobulare, an end continually in fascia pectoralis. Another end in the skin, fixes continually the mammary gland gland during the chest Subcutaneous tissue. These support function and the fixed breast position’s textile fiber knot contracts the organization to be called the breast to hang the ligament. The shallow fascia in-depth located at mammary gland’s deep surface, has the Open texture with the chest greatly myo- fascia shallow layer between to be connected, it may cause the breast both relatively fixed, and can have certain mobility on the thoracic wall. Sometimes, the partial mammary gland gland may pass through the Open texture to penetrate into the chest greatly myo- shallow layer, therefore, undergoes time breast cancer radical operation, should one and excises the chest greatly myo- fascia and the muscle.
