Acromion

The acromion, also known as the acromial process, is a small section of the scapula that extends anteriorly from the spine of the scapula. 

It forms the acromioclavicular joint with the lateral third of the clavicle, and also connects with the coracoid process via the coraco-acromial ligament.
