| Base boundary of axilla | armpit (skin, subcutaneos tissue, axillary fascia) |
| anterior boundary of axilla | Pectoralis major, pectoralis minor, pectoral and clavipectoral fascia |
| Lateral boundary of the axilla | intertubercular groove of the humerus |
| Medial boundary of the axilla | thoracic wall and serratus anterior |
| Posterior boundary of the axilla | superiorly via the scapula and subscapularis Inferiorly via teres major and latissimus dorsi |
| Contents within the axillary sheath | axillary artery & branches Axillary vein & tributaries Brachial plexus (cords and branches) |
| Contents outside of the axillary sheath | Axillary lymph nodes & lymphatic vessels Axillary fat |
