Natural Breast Enlargement - The Magic Formul

Breast shape varies among patients, but knowing and understanding the anatomy of the breast ensures safe surgical planning (see the image below). When the breasts are carefully examined, significant asymmetries are revealed in most patients. The rectus abdominis muscle demarcates the inferior border of the breast. It is an elongated muscle. The overall boundaries of this standard ALND are the chest wall (serratus anterior muscle) medially, axillary vein superiorly, subscapularis muscle plus thoracodorsal and long thoracic nerves posteriorly, and latissimus dorsi laterally. The axillary vein is the major structure defining the superior border of the surgical dissection The breasts are paired structures that lie in front of the anterior thoracic wall over the pectoralis major muscle. In this article, we shall discuss the anatomy of the breast, its nerve supply, blood supply, lymphatic drainage along with various aspects of clinical significance lateral border at mid axillary line; medial border at edge of sternum Deep margin of breast rests on fascia of pectoralis major muscle Breast tissue often extends into axilla (tail of Spence) • In some women, breast tissue is present in subcutaneous tissue and can extend beyond grossly evident breast borders Suspensory (Cooper) Ligament 51. Breast Anatomy Melissa A. Crosby, Glyn Jones EMBRYOLOGY, DEVELOPMENT, AND PHYSIOLOGY EMBRYOLOGY The breast is ectodermally derived. From week 8-10 of embryologic development, breast growth begins with differentiation of cutaneous epithelium of pectoral region. In week 6, milk ridge develops extending from axilla to groin.

1 Anatomy for plastic surgery of the breast. Jorge I. de la Torre, Michael R. Davis. Synopsis. Size, symmetry, proportionality and the location of the breast and its landmarks on the chest wall all play a role in the attractiveness of the breast. Knowledge of breast anatomy, in particular, the vascular pedicle and location of the nerves. The breast is a modified cutaneous exocrine gland composed of skin and subcutaneous tissue, breast parenchyma, and stroma, including a complex network of arteries and veins (4). The margins of the adult breast are defined by the second and seventh intercostal spaces longitudinally and between the sternum and anterior axillary fold transversely The breast extends from the second rib to the inframammary fold located at the level of the sixth or seventh rib [ 13 - 15 ]. Medial extension of the breast is to the sternum, and the lateral border extends to the mid-axillary line terminating as the axillary tail of Spence

The breast is a mound of fibrous stroma with adipose, ductal, and glandular tissue overlying the anterior chest wall (Fig. 5-1). It often extends to the axillary tail (tail of Spence). FIGURE 5-1 Cross-Sectional Anatomy of the Breast pioneered. These descriptions, however, fail to explain the three-dimensional fascial system in the breast. The authors set out to discover and describe a theory of superficial fascia structures responsible for breast shape.

The breasts of an adult woman are milk-producing, tear-shaped glands. They are supported by and attached to the front of the chest wall on either side of the breast bone or sternum by ligaments. They rest on the major chest muscle, the pectoralis major.. The breast has no muscle tissue.A layer of fat surrounds the glands and extends throughout the breast

The upper and lateral breast borders are relatively mobile, but the inferior and medial breast borders are relatively fixed. All four borders can be changed with certain surgical maneuvers, and these have been measured and analyzed Here is what we have learned from Breast Anatomy: The breasts of an adult woman are milk-producing, tear-shaped glands. A layer of fatty tissue surrounds the breast glands and extends throughout the breast, which gives the breast a soft consistency and gentle, flowing contour

The anatomy of the breast must be well understood to understand the disorders that affect this organ and develop a plan for breast surgery. When examined, some degree of asymmetry is noted in most breasts. Other deformities include kyphosis, scoliosis, or some type of pectus deformity. The majority of the breast consists of glandular (milk. The breast is one of two prominences located on the upper ventral region of the torso of primates.In females, it serves as the mammary gland, which produces and secretes milk to feed infants. Both females and males develop breasts from the same embryological tissues. At puberty, estrogens, in conjunction with growth hormone, cause breast development in female humans and to a much lesser extent. The significant anatomy of the ADM-assisted expander-implant technique involves the anatomic borders of the breast mound, the associated blood supply, and the nerve supply. See Breast Anatomy for.
