The Axilla
Slide2OBJECTIVES
Identify the walls of the axilla and how structures traverse them
Study the course and branches of the axillary artery and recognize its important relations.
Understand the arterial anastomosis around the scapula & shoulder joint
Locate & study the groups of axillary lymph nodes
Study the nerves of the upper limb and deduce their root value by understanding the arrangement of the brachial plexus
