Milk exits the breast through the nipple, lf is surrounded by a pigmented area of skin called the areola. The size of the areola can vary widely among women. The areola contains modified sweat glands known as Montgomery's glands. These glands secrete oily fluid that lubricate and protect the nipple during breastfeeding.
The tissue composition ratios of the breast also vary among women. Some women's breasts have varying proportions of glandular tissue than of adipose or connective tissues. The fat-to-connective-tissue ratio determines the density or firmness of the breast.

The nipple of the breast is surrounded by the areola nipple-areola complex. The areola has many sebaceous glands, and the skin color varies from pink to dark brown. The basic units of the breast are the terminal duct lobular units TDLUswhich produce the fatty breast milk. They give the breast its offspring-feeding functions as a mammary gland.
They are distributed throughout the body of the breast. The terminal lactiferous ducts drain the milk from TDLUs into 4—18 lactiferous ducts, which drain to the nipple. The milk-glands-to-fat ratio is 2: In addition to the milk glands, the breast is also composed of connective tissues collagenelastinwhite fat, and the suspensory Cooper's ligaments. Sensation in the breast is provided by the peripheral nervous system innervation by means of the front anterior and side lateral cutaneous branches of the fourth- fifth- and sixth intercostal nerves.
The T-4 nerve Thoracic spinal nerve 4which innervates the dermatomic areasupplies sensation to the nipple-areola complex. The axillary lymph nodes include the pectoral chestsubscapular under the scapulaand humeral humerus-bone area lymph-node groups, which drain to the central axillary lymph nodes and to the apical axillary lymph nodes.

The space between the breast and the pectoralis major muscle, called retromammary spacegives mobility to the breast.

The inframammary fold, where the lower portion of the breast meets the Thw, is an anatomic feature created brwasts the adherence of the breast skin and the underlying connective tissues of the chest; the IMF is the lower-most extent of the anatomic breast.

Even cosmetic enhancement notwithstanding, breasts are bigger than ever, and girls are getting them at increasingly younger ages. These recent dramatic changes are the heft of Williams' book, although she also covers evolutionary basics, like why we have them, what they're made of and how they work. It's an interesting and engaging read peppered with factoids the kid from "Jerry Maguire" would no doubt appreciate e. Occasionally, it veers into technical territory that will put some readers to sleep, but overall it's a much-needed look at why breasts matter more than we realize, even in our boob-obsessed society.
I spoke with Williams by phone about the myth of the perfect pair, growing bra sizes and toxic breast milk. One of the trickiest questions posed by the book is the simple one of why breasts exist. After all of your research, where do you stand on that question? There are no other mammals in which breasts are sexually selected. It just makes sense that in our deep evolutionary past we really needed those extra few percentages of fat, and breasts gave us a place to put that, and really helped gestate and lactate the human infant, which has these unique fat requirements.
The mammary gland in the breast in humans is filled with estrogen receptors and those actually make fat. Speaking of plastic surgeons: You actually had one evaluate your own breasts for the book. What was that like? It was really bizarre and funny. I always thought my breasts were sort of perfectly fine. When did breast implant mania really begin? The first silicon breast implant was performed inso 50 years ago. It was up and running pretty quickly after that. It was particularly popular among women who made their living onstage -- the go-go dancers and the burlesque dancers and the topless dancers and then Hollywood.
Eventually it leaked into the broader culture, and certainly by the '70s and '80s women were going for this. More than this, attitudes around breasts have shifted significantly over time, the only constant being that breasts feed babies. In the Classical world, the breast was primarily symbolic of motherhood.

Nero was said to have kissed the breasts of his mother before attempting to assassinate her. Todgers and titties Classicist authority par excellence Mary Beard noted that as far as statues went in the ancient world, you would be far more likely to see a todger than a titty, and that there were no sculpted female nudes until the 4th century BC as it was all about the boys. Attitudes change over time During the reign of Charles II, English ladies sported necklines so low that they decorated their nipples with pots of carnelian make up.
Unless you too sport workwear cut so low you need to invest in nipple makeup, we must concede that attitudes to the almighty nip has changed over time. The Chinese tradition of foot binding, for example, was strongly fetishized and sex acts featuring tiny feet are seen in many sex manuals of the Qing Dynasty Lip plating still occurs in a few indigenous tribes across Africa and the Amazon rain forest where it is regarded as a sign of beauty and sexual maturity. Other cultures around the world have eroticised hair, ankles, buttocks, fat, lips, necks and even as I recently discovered back dimples.
Breasts are secondary sex characteristics, but how do we account for the sexualising of hair or ankles? This is because what we find sexy is cultural and changeable, not biological.
