What bone structure do the Coracoclavicular ligaments primarily support?

The Coracoclavicular ligaments primarily support the clavicle. These ligaments consist of two distinct bands: the trapezoid ligament and the conoid ligament, which connect the coracoid process of the scapula to the clavicle. Their main function is to provide stability to the acromioclavicular joint, allowing for proper movement and support between the shoulder girdle and the collarbone. This is crucial for maintaining the integrity of the shoulder joint during various arm movements.

In contrast, while the scapula is indeed part of the shoulder girdle and is indirectly affected by the stability provided by the coracoclavicular ligaments, they do not directly support this bone. The humerus and radius are bones of the upper arm and forearm, respectively, and are not related to the function of the coracoclavicular ligaments, which are specifically designed to stabilize the connection between the scapula and clavicle.
