Arteries of a Female's Mammary Gland

Description

Radiating through the glandular lobules and converging toward the nipple and areola, the arterial supply of the female mammary gland is shown in relation to the lactiferous ducts and surrounding adipose tissue. Medially, perforating branches consistent with the internal thoracic artery course anterior to the pectoralis major and enter the breast parenchyma, while laterally the breast is supplied by branches aligned with the lateral thoracic artery and the pectoral branch of the thoracoacromial trunk. A finer arteriole network distributes through the fibroglandular tissue, with Cooper’s ligaments spanning from dermis to the deep fascia overlying the pectoral muscles. Orientation is clear. Clinical work on the breast is inseparable from this vascular map because most incisions, resections, and reconstructions either respect or disrupt these territories. Surgeons planning reduction mammoplasty and nipple-areolar complex pedicles track the dominant perforators and lateral branches to preserve perfusion, and the same pathways explain patterns of hematoma after biopsy or lumpectomy. Radiologists and breast imagers also reference these courses when correlating contrast enhancement or suspected vascular lesions, and when teaching why internal mammary chain nodes matter in oncologic staging. Use this illustration for anatomy and surgical teaching in gross anatomy, breast surgery, and plastic surgery courses, and as a figure in journal articles or patient education materials describing lumpectomy approaches, pedicle design, or post-operative vascular complications of the chest wall and breast. It also suits grant figures and slide decks where you need an accurate relationship between breast parenchyma, pectoral fascia, and named arterial sources.
