Form, Function and Appearance of Breasts
Due to their general pronounced appearance, most individuals associate breasts as a part of a woman's anatomy, however, men have breasts as well. The obvious visual factor in the Breast Size, is based upon the amount of development. The formations of breasts, within the embryo, are the same for females and males, in that the foundation origin is equally derived from in a homologous manner, utilizing the same embryological progressive tissue. Amid the growth of the embryo, it is the glands unique to the female sex that lead to the distinct difference in function. Such glands are known as sudoriferos, in having the eventual ability to produce milk, unlike those in the male anatomy. In a distinct summary, this brief reference defines the Breast Size between the sexes, based upon biological function.
The natural structure of the female breasts begins from the chest wall, through the pectoral muscles. By way of development, lobules increase in their respective size. Added to the structure of the breasts, are the areolas and nipples. Areolas, ranging from dark brown to pink in outward color, possess glands that are sebaceous. Areolas are universal in both females and males. Nipples, also, are apparent to each
sex; though serve a vital function for females, which has a complex formation in its ultimate purpose.
Each nipple can contain from 4 to 18 lactiferous ducts, with the individual ducts having an independent opening. The anatomical design of each nipple, with its ducts, is weaved in a pattern that is comparable to such of the tangled root system of deciduous growth. Ducts or nipples do not hold the eventual milk; though serve as a canal or passageway for the milk to be distributed to the potential infant. Inwards of the female breasts are the mammary glands. These are the glands that produce milk, and are present throughout the entire Breast Size or mass of the breast, and, like that of a funnel, reach a density of two-thirds of the related tissue at the inward point of the nipple. Included amid the mass of the overall Breast Size, in both females and males, are the arteries, to include the internal thoracic, lateral thoracic, thoracoacromial, and posterior intercostals. Veins within the breasts include axillaries and internal thoracic, as well as intercostals. The nipples in the breasts of both males and females contain a sizeable concentration of nerves and blood vessels, which react to sexual stimulation, by becoming erect. Cold temperatures can also create erectness to the nipples, though not in any relevance to sexual stimulation. Rounding out the volume of the breasts, or, rather, overall Breast Size, in either sex, are skin, muscle and fatty tissue.
In summarization, it is the mammary glands and ducts, along with the connecting tissue groups of adipose, collagen and elastin, combined with what is referred to as Cooper's ligaments that distinctly define the differences, both internal and external, in the Breast Size of women and men.
Formation, as to the outward shape of the female breasts, is significantly impacted by the support of the Cooper's ligaments, enhanced by the deeper-seated chest, as a foundation. Internally, the breasts are connected, at their base, to the walls of the chest, by a depth of what is termed as fascia, which lies atop the pectoral muscles. Breast Size, in relation to support, is distinguished by whether the breasts rest on or suspend from the chest. Breasts that project in a near horizontal presentation are well rounded, and, generally, are the norm within young and adolescent females.
In the case of lower presented breasts, a degree of the overall Breast Size, in relationship to weight, relies on support from the chest, particular for the lower portion of the breasts, as they are deeply attached at their respective basis. As the volume of weight is proportioned over an area of some mass, any strain is greatly reduced. Common to both the breasts of males and females is in how the thoracic cavity angles, in a progressive manner, out and away from the upper part of the breastbone, and downward to the lower ribs, which provides enhanced support.
Anatomically, the distinguishing line, referred to as the inframammary fold or crease, is created by skin elements and connective and deep tissue, which, in its varying and normal degrees, determine, so to express, Breast Size. The position of the nipples, in relationship to the inframammary line, is termed, ptosis, and varies widely amongst individuals.
Functionality of the breasts of females is, of course, in their production of milk, which prepares for such benefit during pregnancy. Human breasts are a considerable component and enhancement amid sexual interactions, in the modes of appearance, stimulation, sensitivity and eroticism.
Of all beings, developing or developed humans have the distinct uniqueness of being the only living species to present permanently accentuated Breast Size.
