What is the function of the clavicle

It serves as a rigid support from which the scapula and free limb suspended; an arrangement that keeps the upper limb away from the thorax so that the arm has maximum range of movement. Acting as a flexible, crane-like strut, it allows the scapula to move freely on the thoracic wall. Covering the cervicoaxillary canal, it protects the neurovascular bundle that supplies the upper limb. Transmits physical impacts from the upper limb to the axial skeleton.
