Question

describe the function of the costoclavicular ligament. it allows for unrestricted elevation of the clavicle it allows for excessive scapular protraction it reinforces the superior aspect of the joint capsule it checks elevation of the clavicle and prevents medial and lateral movement

Explanation:

The costoclavicular ligament stabilizes the sternoclavicular joint by limiting excessive movement of the clavicle. It restricts upward elevation and prevents unwanted medial/lateral shifting of the clavicle, while the other options describe incorrect functions (it does not allow unrestricted elevation or excessive protraction, nor does it reinforce the superior joint capsule).

Answer:

It checks elevation of the clavicle and prevents medial and lateral movement
