Question: 1 / 570

What is the primary role of the clavicle?

To connect the arm to the shoulder

To support the wrist

To protect the heart

To stabilize the shoulder

The primary role of the clavicle, commonly known as the collarbone, is to stabilize the shoulder. It acts as a crucial connector between the arm and the trunk of the body, allowing for a wide range of motion in the shoulder joint. By providing structural support, the clavicle helps maintain the proper position of the scapula (shoulder blade) and allows the muscles that move the shoulder and arm to function effectively.

While the clavicle does help in connecting the arm to the shoulder, its main purpose is more focused on stabilization rather than just connection. It does not support the wrist directly, nor is its primary function to protect the heart, although it does provide some protective coverage for structures within the thorax. Understanding the role of the clavicle in stabilizing the shoulder offers insight into its significance in upper limb movement and overall shoulder mechanics.
