Medical Note on Nipples
The small “bumps” in the area of the areola are known as “Tubercles of Montgomery.” The areola has a number of smooth muscles cells that cause the nipple to stand up more prominently with stimulation. The pigmented area also contains an increased number of oil glands that keep the nipple from becoming chaffed with sucking. The pigment of the areola & nipple becomes more darkly pigmented and red, and more highly contractable, after puberty, thus indicating a fertile female ready for mating. ~JD Better
