Final answer:
The bone that articulates with the clavicle laterally is the scapula, specifically at the acromial end of the clavicle which joins with the acromion, part of the scapula.
Step-by-step explanation:
The bone that articulates with the clavicle laterally is the scapula. Specifically, the lateral or acromial end of the clavicle articulates with the acromion of the scapula, forming the acromioclavicular joint. The clavicle supports the scapula, which in turn holds the shoulder joint superiorly and laterally from the trunk, providing a wide range of motion for the upper limb. Additionally, the clavicle aids in transmitting forces from the upper limb to the axial skeleton and protects underlying nerves and blood vessels.
Clavicle, also known as the collarbone, is an elongated bone that articulates with the manubrium of the sternum medially. The lateral end of the clavicle that articulates with the acromion of the scapula receives indirect support from the coracoclavicular ligament, a strong band of connective tissue that anchors the clavicle to the coracoid process of the scapula, providing stability to the joint.
