Though it is present in males it is not functional. Extent Transversely from lateral margin of sternum to midaxillary line Vertically from 2 nd to 6 th rib A small extension into the axilla is known as Axillary tail Structure- The mammary gland is made up of modified sweat glands and fibro-fatty tissue and lies wholly in the superficial fascia. In the central part there is a projection called the nipple and around it a pigmented area known as areola. The gland has 18 to 20 lobes, seperated by connective tissue. Each lobe is made up of a number of acini which opens separately through the nipple by lactiferous duct and presents a dilatation close to the terminal part called lactiferous sinus.
