In this lecture Warda Naz comes up with breast anatomy. At sqadia.com, this V-learning lecture initially highlights the anatomical location of breast. Then structure of breast is discussed. After that breast quadrants are pursued. Subsequently, lymphatic drainage of breast comes under consideration. Warda Naz also notify about breast anomalies such as amastia, polythelia, nipple inversion and Poland’s syndrome.
Anatomically, breast is located in superficial fascia of the pectoral region. Warda Naz elaborates the anterior, medial, posterior and lateral boundaries of breast. Pectoralis major, serratus anterior, and external oblique are the muscles which lies deeper to the breast. Retro mammary space is also conversed about.
Structure of Breast
Nipple is the conical projection located on the skin just below the centre of the breast. Skin surrounding base of nipple is areola. It is pigmented in circular area. Then comes the parenchyma which is a glandular tissue composed of 15-20 lobes. After that, Warda Naz talks about histology of parenchyma.
In the beginning, quadrants of breast are explained diagrammatically. Then axillary tail of spence is discussed. Stroma of breast is partly fibrous and partly fatty. Following this, arterial supply of breast is highlighted along with venous drainage of breast.
Lymphatic Drainage of Breast
Lymph nodes are small glands that are found in groups throughout your body. Axillary lymph nodes constitute about 75%. Superficial lymphatic vessels drain skin. Deep lymphatics drain parenchyma, nipple and areola. Important lymphatic structures and lymphatic drainage is discussed along with age related changes of breast.
Amastia, polymastia, athelia, polythelia, and gynaecomastia are the developmental anomalies of breast. Nipple inversion can be corrected for cosmetic purposes, but it leads to inability to breast feed. In Poland’s syndrome, there is absence of Chest wall and shoulder girdle muscles. Lastly, breast infection and pain is illuminated.
