Clavicle

Dr. Morton, The Noted Anatomist, explains the clavicle, also known as the collarbone. The clavicle forms part of the pectoral girdle and connects the upper limb to the trunk. It has two ends: the acromial end, which forms the acromioclavicular joint, and the sternal end, which forms the sternoclavicular joint. The clavicle acts as a strut, providing support and stability to the upper limb, and transmits forces from the limb to the axial skeleton. It is prone to fractures, especially in the middle to lateral third, due to its role in absorbing shocks. The video concludes with a review of the clavicle's anatomy and function.
