areola

Working with the Personal Genome Project, she has collected measurements and images of the areolas of 150 people so far. One initial finding is that the diameter of the areola seems unrelated to the number of areola glands — the small bumps in the skin surrounding the nipple.

The tubes or elongated spaces of which we have spoken, are not distended with any fluid, but are merely moistened in the same way as the areolas of ordinary areolar tissue.
