Final answer:
The clavicle, or collarbone, articulates with the acromion of the scapula at the acromioclavicular joint, with the lateral end of the clavicle meeting the acromion to allow shoulder mobility.
Step-by-step explanation:
The clavicle, also known as the collarbone, articulates with the acromion of the scapula at the acromioclavicular joint. Specifically, the lateral end of the clavicle, also referred to as the acromial end, intersects with the acromion, which is a bony projection on the scapula. This articulation is crucial for the mobility and stability of the shoulder, permitting a range of movements and serving as a site of attachment for ligaments and muscles.
The integrity of the acromioclavicular joint is maintained by the coracoclavicular ligament, which significantly contributes to the joint's stability. However, this joint can be susceptible to injury, especially from impacts that occur during contact sports, potentially leading to what is known as a "shoulder separation," where the scapula and clavicle become misaligned.
