MadSci Network: Anatomy |
Interesting question! I found your answer at: http://www.phys.com/health/breasthealth/anatomy/structure/elements/elements.html and, I quote from it here: While the skin covering the breast is smoother, thinner, and more translucent than on most of the rest of the body, the areola's skin is even thinner and has complex sweat glands and sebaceous glands (which secrete an oily lubricating substance called sebum) and hair follicles. The surface of the areola is marked by a number of small bumps called the tubercles of Montgomery. These are sweat and sebaceous glands that become more prominent in the second half of the menstrual cycle and grow throughout pregnancy. Erin
