Descriptive anatomy of the axillary artery and its branches in 7 min. Drawing on whiteboard.
The axillary artery is the main artery of the upper limb. It beggins at the outer border of the first rib as the continuation of subclavian artery and ends by becoming the brachial artery at the lower border of teres major. During its course through axilla it is crossed on its superficial aspect by the pectoralis minor muscle, which divides it into three parts. The axillary vein is medial to the artery and the cords of brachial plexus are arranged around the second part of the artery.
