Hello again, everyone! It’s Matt from Kenhub, and in this tutorial,
we will discuss the anatomy, definition, and function of the clavicle. The clavicle or collar bone, as it is often
called, is a curvy bone located at the base of the neck. It is classified as a long bone, but it is
actually relatively short. It runs from the sternum at the medial line
to the acromion of the scapula, and there is one on each side of the sternum. Some of the landmarks of this bone are the
prominence where ligaments attach to the bone. They are found on the inferior surface of
the bone and include the conoid tubercle (near the acromial end), the trapezoid line also
on this end, and the impression for the costoclavicular ligament on the sternal end. The names of these bony prominences echo the
ligaments that attached at these points. The function of the clavicle is to attach
the arms to the trunk. It also protects the neurovascular structures
which supply the arm and transfers the force from the upper limb to the axial skeleton. Because it lies so close to the surface of
the body, the length of the clavicle can be easily palpated and is visible on some people. It is the most commonly fracture bone in the
body because of its location and its function as a stress absorber. This video is more fun than reading a textbook,
