Internal Mammary Artery

Monday, January 9, 2012

The internal mammary artery, also known as the internal thoracic artery, is one of a pair of blood vessels that originates from the subclavian artery. It runs down along the sternum, giving off the sternal branches and perforating branches as it goes, to finally divides into two smaller arteries: the musculophrenic artery and the superior epigastric artery. The internal mammary artery supplies the anterior chest wall and the breast with oxygenated wall.
