In females, the breasts contain the mammary glands — an accessory gland of the female reproductive system. The mammary glands are the key structures involved in lactation. In this article, we shall look at the anatomy of the breasts — their structure, innervation, vascular supply and any clinical relevance. The breast is located on the anterior thoracic wall. It extends horizontally from the lateral border of the sternum to the mid-axillary line. Vertically, it spans between the 2nd and 6th costal cartilages. It lies superficially to the pectoralis major and serratus anterior muscles. At the centre of the breast is the nipple , composed mostly of smooth muscle fibres. Surrounding the nipple is a pigmented area of skin termed the areolae. There are numerous sebaceous glands within the areolae — these enlarge during pregnancy, secreting an oily substance that acts as a protective lubricant for the nipple.
