Question

Explanation:

True anatomic joints have a synovial cavity, articular cartilage, and a joint capsule. The glenohumeral, sternoclavicular, and acromioclavicular joints are all synovial (true) joints of the shoulder complex. The scapulocostal joint is a functional (non-anatomic) joint, referring to the sliding relationship between the scapula and the ribcage without a formal joint structure.

Answer:

Scapulocostal joint
