Lactation is the process by which milk is synthesized and secreted from the mammary glands of the postpartum female breast in response to an infant sucking at the nipple. The lobes lobules and bulbs are all linked by thin tubes called ducts. Tiny openings in the nipple allow milk to flow.

The Anatomy and Physiology of the Breast. The structure of the breast. The nature of the superficial fascia system that surrounds the breast and its attachments to the chest were studied in 12 cadaver breast dissections and in clinical cases of both cosmetic and reconstructive breast.

Within these tissues are milk-producing cells. Figure 11 shows the different parts of the breast. Development of the Human Breast.

Surrounding the nipple is the areola an area of darker skin that becomes both larger and darker during pregnancy. Fibrous or supportive or connective tissue is the same tissue that ligaments and scar tissue are made of.

Within each lobe are many smaller lobules which end in dozens of tiny bulbs that can produce milk. Each breast consists of tissue overlying the chest wall muscles the pectoral muscles. The epithelial component of the tissue consists of lobules where milk is made which connect to ducts that lead out to the nipple.

Fewer milk ducts average 9. The breast is a modified sweat gland located in the superficial fascia of the anterior chest wallThe major portion of the breast tissue is situated between the second and third rib superiorly the sixth and seventh costal cartilage inferiorly the anterior axillary line laterally and the sternal border medially. The parenchyma forms a system of branching ducts eventually leading to secretory acini development and the stroma consists mainly of adipose tissue providing the environment for development of the parenchyma.

Doctors refer to all non-fatty tissue as fibroglandular tissue. Breast milk provides ideal nutrition and passive immunity for the infant encourages mild uterine contractions to return the uterus to its pre-pregnancy size ie involution and induces a substantial metabolic. Each breast extends superiorly to the.

The amount of fat. It extends horizontally from the lateral border of the sternum to the mid-axillary lineVertically it spans between the 2nd and 6th costal cartilagesIt lies superficially to the pectoralis major and serratus anterior muscles. It grows along two ridges one on either side running from the armpit axilla to the groin.

1 2 3 These building blocks of the breast are recognized. The human breast consists of parenchymal and stromal elements. The authors set out to discover and describe a theory of superficial fascia structures responsible for breast shape.

Anatomy of the breast Normal anatomy. Range 4-18 Milk ducts branch closer to nipple 65 of glandular tissue within 30mm radius from base Milk ducts are small and do not display lactiferous sinuses dilated portion beneath nipple-only dilate with milk ejection reflex.

Located between the second and 6th rib. Areola surrounds nipple with sebaceous glands montgomery glands- secretes protective lipid material Glandular Tissue Fibrous Tissue suspensory ligaments Adipose tissue. The remaining part is made up of fatty tissue.

The nipple anatomy is adjusted to support the function of the breastThey are surrounded by a pigmented circular region of skin called the areola which becomes even more pigmented and prominent during pubertyThe areola shows small punctual elevations on its surface which are produced by the many areolar glands. He described ligamenta suspensoria which connected to the skin and muscle.

Womens breasts are made of specialized tissue that produces milk glandular tissue as well as fatty tissue. Breast milk provides ideal nutrition and passive immunity for the infant encourages mild uterine contractions to return the uterus to its pre-pregnancy size ie involution and induces a substantial metabolic. There are literally thousands of drawings of the breast its blood supply lymphatic drainage and regional nerves that can be found in anatomy books and textbooks on breast disease.
