The shoulder joint, specifically the glenohumeral joint, allows for a wide range of motion, including rotation of the arm that can effectively reach 360 degrees when considering the entire range of movement. This rotational capability is due to its ball-and-socket structure, which provides a high degree of flexibility. However, while the arm can move in a circular motion, it's important to note that the actual rotation of the joint itself is limited by muscle and ligament constraints.
