It crosses the axillary space and continues distally along the medial aspect of the limb. Below are the branches of the axillary artery.

It crosses the axillary space and continues distally along the medial aspect of the limb. There are a number of branches of the axillary artery. The '''external thoracic a.''' and the '''lateral thoracic a.'''both have branches to the thoracic wall. The  '''subscapular a.''' supplies the muscles of the shoulder running dorsally on the caudal border of the scapula between the teres major and subscapularis muscles. The axillary a. changes its name to '''brachial a.''' at the point of the teres major tuberosity,  running along the medial aspect of the humerus and then along the craniomedial aspect of the elbow and the forearm before changing its name to the '''median a.'''.
