In human anatomy, the acromion (from Greek: akros, "highest", ōmos, "shoulder", plural: acromia) is a bony process on the scapula (shoulder blade). Together with the coracoid process it extends laterally over the shoulder joint. The acromion is a continuation of the scapular spine, and hooks over anteriorly..
Likewise, people ask, what is the purpose of the acromion?
The acromion of the scapula is a large bony projection on the superior end of the scapula. It is an important landmark of the skeletal system and a muscle attachment point essential to the function of the shoulder joint. The acromion also forms the acromioclavicular (AC) joint with the clavicle.
Subsequently, question is, what is an acromion fracture? The acromion is a large bony projection on the superior end of the scapula. Acromion fractures may occur as a result of shoulder trauma and overuse injuries. Acromion fractures may occur with glenoid process, scapula or clavicle distal fractures and disruption of superior shoulder suspensory complex.
In this way, where is the acromion found?
The acromion process is a bony structure located at the top of the scapula. This process provides an articulation (connection) point with the clavicle, which also produces the acromioclavicular joint.
What is the Acromial area?
the acromial region encompassing the shoulder, the brachial region encompassing the upper arm, the olecranal region encompassing the back of the elbow, the antebrachial region encompasses the back of the arm. and the manual or manus region encompassing the back of the hand.

Overhead activity of the shoulder, especially repeated activity, is a risk factor for shoulder impingement syndrome.Why is it called the coracoid process?
The coracoid process (from Greek κόραξ, raven) is a small hook-like structure on the lateral edge of the superior anterior portion of the scapula (hence: coracoid, or "like a raven's beak").
