The collarbone (clavicle) is one of the main bones of the shoulder joint.
The collarbone holds the shoulder up and back, and along with the shoulder
blade (scapula) and acromioclavicular (AC) joint helps increase the stability
and strength of the shoulder. The collarbone also protects nerves and blood
vessels from the neck to the shoulder.
