The nipple is a raised region of tissue on the surface of the breast from which, in females, milk leaves the breast through the lactiferous ducts to breastfeed an infant. Male mammals also have nipples but without the same level of function, and often surrounded by body hair. The nipple is surrounded by the areola , which is often a darker colour than the surrounding skin. In humans, the nipples of both males and females can be sexually stimulated as part of sexual arousal. In many cultures, human female nipples are sexualized , [4] or regarded as sex objects and evaluated in terms of their physical characteristics and sex appeal. In mammals , a nipple also called mammary papilla or teat is a small projection of skin containing the outlets for 15—20 lactiferous ducts arranged cylindrically around the tip. Marsupials and eutherian mammals typically have an even number of nipples arranged bilaterally, from as few as 2 to as many as The skin of the nipple is rich in a supply of special nerves that are sensitive to certain stimuli: these are slowly-adapting and rapidly-adapting cutaneous mechanoreceptors. Mechanoreceptors are identified respectively by Type I slowly-adapting with multiple Merkel corpuscle end-organs and Type II slowly-adapting with single Ruffini corpuscle end-organs , as well as Type I rapidly-adapting with multiple Meissner corpuscle end-organs and Type II rapidly-adapting with single Pacinian corpuscle end-organs.
