Acromion process
The acromion process, or simply the acromion, is an anatomical feature on the scapula.
It is a continuation of the scapular spine, and hooks over anteriorly. The acromion articulates with the clavicle to form the acromioclavicular joint.
The acromion process of bats (Mammalia: Chiroptera) is particularly elongated compared to that of humans.
