The Scapulothoracic Joint [+ Review of SC and AC Joints]

The video provides a comprehensive review of the SC and AC joints, including their ligaments and stabilizing structures. It explains the scapulothoracic articulation, emphasizing its role as a muscular joint rather than a synovial one. The video also covers the movements of the scapula, the muscles involved, and the function of bursa in reducing friction. Key anatomical landmarks and ligaments are highlighted to aid understanding of joint stabilization and movement.
