Anatomy and Histology of a Normal Breast Gland

breast gland is a specialized organ composed of glandular, connective, and adipose tissue, designed primarily for milk production in females. Here’s a breakdown of its anatomy and histology: Anatomy of the Breast Gland Lobes & Lobules – The breast contains 15-20 lobes, each made up of smaller lobules that produce milk. Lactiferous Ducts – These ducts transport milk from the lobules to the nipple. Suspensory Ligaments (Cooper’s Ligaments) – Provide structural support to the breast. Adipose Tissue – Surrounds the glandular structures, giving the breast its shape. Blood Supply – Mainly from the internal thoracic, lateral thoracic, and intercostal arteries. Lymphatic Drainage – Includes axillary, parasternal, and subclavian lymph nodes, crucial for immune defense. Histology of the Breast Gland Ductal-Lobular System – Composed of ducts and acini, lined by: Luminal epithelial cells (inner layer) – Responsible for milk secretion. Myoepithelial cells (outer layer) – Aid in milk ejection. Basement Membrane – Supports epithelial cells and maintains tissue integrity. Stroma – Includes fibrous connective tissue and adipose tissue, providing structural support. Hormonal Influence – The breast undergoes changes during puberty, pregnancy, and menopause #Breast
