Sunday, January 8, 2012

The lateral thoracic artery is an oxygen-rich blood vessels that arises from the axillary artery and runs along the lower border of the pectoralis minor muscle, giving off branches to the axillary limph nodes and subscapularis muscle. These branches anastomoses with the subscapular, intercostal arteries, and internal thoracic artery. The lateral thoracic artery supplies the lateral structures of the thorax and breast.
