What is the function of the clavicle?

The functions of the clavicle are to provide support for free range movement of the arms and to protect the neurovascular bundle. The flat horizontal bone is part of the shoulder and is also referred to as the collarbone.

The clavicle connects the shoulder blade to the sternum and acts as a strut to allow free movement of the arm. Because the clavicle covers the cervicoaxillary canal, the neurovascular bundle that contains veins, arteries and lymphatics is protected.

The location of the clavicle makes it very susceptible to injuries. No bone on the human body is broken more often that the clavicle.
