To which two points does the clavicle attach?

The correct answer identifies the manubrium and acromion process as the two points where the clavicle attaches. The clavicle, often referred to as the collarbone, plays a significant role in connecting the upper limb to the trunk. It articulates with the manubrium, which is the upper part of the sternum, at the sternoclavicular joint. This joint allows for a range of motion of the shoulder girdle.

Additionally, the clavicle also connects to the acromion process of the scapula at the acromioclavicular joint. This joint is critical for shoulder mobility and stability, enabling the arms to move freely while maintaining a stable connection to the thoracic skeleton.

In summary, the attachment points of the clavicle are integral to the overall function and biomechanics of the upper body, facilitating movement while providing structural support.
