Clavicle

Learning objectives

This study unit will help you to:

1. Learn about the location and function of the clavicle.
2. Identify the bony features of the clavicle.
3. Learn about the joints that the clavicle forms with the adjacent bones.

Watch video

The clavicle is an S-shaped long bone that connects the upper limb to the trunk. It rests horizontally between the sternum and the acromion of the scapula. Its position makes the clavicle the main connection between the axial skeleton and the pectoral girdle. This enables the clavicle to transfer the weight from the upper limbs to the axial skeleton.

The video tutorial below will provide you with an overview of the clavicle.

Summary

Key points about the clavicle
Parts Sternal (medial) end, shaft, acromial (lateral) end
Bony landmarks Trapezoid line, conoid tubercle, groove for subclavius muscle, impression for costoclavicular ligament
