the

Clavicle Bone - Location, Definition & Function - Human Anatomy | Kenhub

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.
