Complete Set of Mammary Glands, Anterior View

Description

Bilateral mammary glands are rendered on the anterior thoracic wall, with the glandular lobules radiating toward the nipple and areola and converging into lactiferous ducts deep to the skin. Laterally, the breast parenchyma extends toward the anterior axillary line as the axillary tail, while posteriorly the retromammary space separates it from the fascia over pectoralis major. Superficial veins course within the subcutaneous tissue, and segmental vessels and cutaneous nerves are traced as they approach the areolar complex. Lymphatic channels run from the subareolar plexus toward axillary nodes, with medial drainage implied toward parasternal pathways. Understanding these relationships matters when you are mapping breast cancer spread and planning incisions. Axillary node involvement follows dominant lymphatic drainage from the lateral quadrants, while medial lesions can reach internal thoracic (parasternal) nodes, a pattern that affects staging and radiation fields. Surgical landmarks also sit in plain view here, the pectoral fascia deep to the gland, and the trajectory of intercostal nerves that can be injured during mastectomy or reduction mammoplasty, with postoperative numbness often centered around the nipple-areola complex. Use this plate for gross anatomy and breast imaging teaching, correlating ductal anatomy and lymphatic drainage with mammography, ultrasound, and MRI reporting language, and for oncology or plastic surgery publications that need a clean anterior reference of breast tissue on the thorax. It also fits patient education materials explaining sentinel lymph node biopsy and the rationale for axillary evaluation. Anatomical accuracy verified by SciePro's Medical Advisory Board.
