Question

List 2 ligaments that help stabilize the shoulder complex.

a) Anterior cruciate ligament and posterior cruciate ligament
b) Medial collateral ligament and lateral collateral ligament
c) Coracoclavicular ligament and coracoacromial ligament
d) Ulnar collateral ligament and radial collateral ligament

Answer 1

Option C. The coracoclavicular ligament and the coracoacromial ligament are two key stabilizers of the shoulder complex, with the former providing significant support to the acromioclavicular joint.

Step-by-step explanation:

The two ligaments that help stabilize the shoulder complex are the coracoclavicular ligament and the coracoacromial ligament. The coracoclavicular ligament is a strong band of connective tissue that anchors the coracoid process of the scapula to the lateral clavicle, and it provides important indirect support for the acromioclavicular joint. The coracoacromial ligament also plays a role in supporting the shoulder joint, although it is not specifically listed in the options provided.

The two ligaments that help stabilize the shoulder complex are the coracoclavicular ligament and the coracoacromial ligament. The coracoclavicular ligament runs from the coracoid process of the scapula to the inferior surface of the acromial end of the clavicle. It provides important indirect support for the acromioclavicular joint. The coracoacromial ligament also helps stabilize the shoulder complex by connecting the coracoid process of the scapula to the acromion process.
