Highest Thoracic Artery

Saturday, December 31, 2011

The highest thoracic artery is an oxygen-rich blood vessel which normally arises from the axillary artery. Also known as superior thoracic artery, it travels forward along the upper border of the pectoralis minor; then it runs between it and the pectoralis major. The point of origin of the highest thoracic artery varies according to individuals. Dividing in two smaller branches, it supplies the muscles of the chest wall.
