True or false: collateral ligaments prevent shoulder flexion.

Explanation:
Ligaments provide passive stability and help limit end-range motion rather than actively blocking a primary movement. In the shoulder, stability comes from the joint capsule, coracohumeral ligament, and the glenohumeral ligaments, not from a set of collateral ligaments. Shoulder flexion is mainly produced by the deltoid and other flexor muscles, and the ligaments only come into play to limit how far the arm can go, not to prevent the motion itself. Because of this, the idea that collateral ligaments prevent shoulder flexion is not correct. The statement is false.
