Importance of breast milk
Introduction
Breastfeeding: It constitutes part of each living being. In the course of evolution, each mammal has developed a unique type of milk for each species to ensure its optimal growth and development, there are several elements involved in breastfeeding, both anatomical, physiological, psychological and social. For a better understanding, it is important to know the factors involved in this phenomenon. The breasts are located in the woman in the superior part of the chest, to the right and left of the sternum, in front of the major and minor pectoral muscles, in the interval between the third and the seventh ribs.
Developing
Located at the height of the arms and that are symmetrically located. The breast looks like a semi -sphere, which rests on the thorax on its flat face and presents an eminence in the form of a nipple in the center of its convex face, called a nipple. This fundamental form offers numerous varieties influenced by different physiological states (pregnancies, previous lactations, health status, etc.), for ethnic variations, etc. Outdoor coating (cutaneous). The superficial face of the breast is covered by skin and two external structures are identified: the nipple and the arelola.
Nipple: It rises like a thick papilla in the center of the areola. Directed obliquely back and a little from inside out. With the appearance of a cylinder or cone, rounded at its free end. Externally it is irregular, rough and sometimes it is presented as cracked. This aspect owes to a multitude of furrows and papillae that rise on its surface. At its vertex they can be observed from 12 to 20 holes that are the mouths of the galactoforos ducts. The nipple and areola contain erectile smooth muscle, as well as sebaceous glands. Aréola: It is a cutaneous area that surrounds the nipple, regularly circularly of approximately 15-25mm.
The Aréola has a lot of sebaceous and sweat glands. Sebaceous glands are called Montgomery or Morgagni tubers. During pregnancy these tubers increase in size, their function is to lubricate to protect the skin of the nipple and the harlary during breastfeeding. Subcutaneous tissue. It consists of the adipose layer, which extends throughout the deep face of the skin of the breast, with exception in the area of the Aréola and the nipple. Among the subcutaneous tissue are fibrous conjunctive leaves, which favor breast support. It should be added that they form cells or graves between the skin and the mammary gland, which are occupied by adipose tissue.
conclusion
Therefore, in the breast there is no layer of continuous and uniform adipose tissue, nor a plane that separates the skin and the gland. Mammary gland: the glandular tissue of the breast has an oval shape, where its thickness is maximum in the central region, in its contour is irregular, due to its extensions. It consists of approximately between 15-20 glandular lobes. Each one has functional independence. In addition, there is a system of ducts that transport the milk outside. The ducts in their initial portion are of small caliber, progressively and as they come together increase.
