# Clavicle

The clavicle is commonly called the collarbone and it located in the upper chest region.  The word “clavicle” is latin for “little key” because it rotates like a key when the shoulder and arm are extended.  The clavicle connects to the acromion process of the scapula and the manubrium of the sternum, creating the pectoral girdle, or the attachment point for the upper limbs.

When working with disarticulated skeletons, the clavicle is commonly mistaken for a rib, though one obvious difference is its curvature.
