- The main function of the axilla is to provide a pathway for these structures to pass through.
Shoulder Complex
- The shoulder complex consists of the scapula, humerus, clavicle, and associated muscles and ligaments.
- The components of the shoulder complex work together to provide a wide range of motion and flexibility to the shoulder joint.
Rotator Cuff Muscles Significance
- The rotator cuff muscles are functionally significant because they play a crucial role in maintaining the stability and mobility of the shoulder joint, allowing for a wide range of movements.
