clavicle, scapula and first rib.
What forms the anterior wall of the axilla?
Pectoralis major + minor, clavicle and subclavius muscle.
What forms the posterior wall of the axilla?
scapula, subscapularis and teres major muscles (with tendon of latissimus dorsi)
What forms the medial wall of the axilla?
