Question

explain why the shoulder is considered a complex joint: it has limited range of motion it is only connected to the arm bone it consists of four separate joints working together it is composed of a single large joint

Explanation:

The shoulder is classified as complex because it functions as a combined system of four distinct joints (glenohumeral, acromioclavicular, sternoclavicular, and scapulothoracic joints) that work in unison to enable its wide range of motion. The other options are incorrect: the shoulder has a very wide range of motion, it connects to multiple bones (not just the arm bone), and it is not a single large joint.

Answer:

It consists of four separate joints working together
