What part of the body does the clavicle connect?

The clavicle, commonly known as the collarbone, serves an important function within the skeletal system. It connects the shoulder to the sternum, which is part of the rib cage at the front of the thorax. This connection is crucial for the stability and movement of the shoulder joint, allowing the arm to have a wide range of motion while maintaining structural support.

In terms of anatomy, the clavicle articulates with the acromion of the scapula (shoulder blade) at one end and with the manubrium of the sternum at the other. This configuration acts as a strut to hold the shoulder away from the body, facilitating a greater range of motion for the arm. The role of the clavicle in this connection is essential for various movements involving lifting, reaching, and throwing.

The other options incorrectly describe connections that do not involve the clavicle. The wrist to elbow, hip to spine, and knee to ankle each refer to different parts of the body that are not associated with the function of the clavicle. Thus, the correct understanding of the clavicle's connection to the shoulder and sternum is crucial for comprehending its significance in the musculoskeletal system.
