Acromial process

Acromial Process

The acromial process is a bony projection on the scapula (shoulder blade) that forms the highest point of the shoulder. It is an important anatomical feature in both human and animal anatomy and plays a crucial role in the function and movement of the shoulder joint.

Anatomy

The acromial process is located on the lateral edge of the scapula, extending over the glenohumeral joint. It is a flat and broad structure, which provides attachment for the clavicle (collarbone) and various muscles and ligaments, including the deltoid muscle and trapezius muscle.

Function

The primary function of the acromial process is to provide a point of attachment for muscles and ligaments that control shoulder movement. It also forms part of the acromioclavicular joint, which allows for a wide range of motion in the shoulder.

Clinical Significance

Injuries or abnormalities of the acromial process can lead to a variety of medical conditions. For example, acromioclavicular joint dislocation can occur if the ligaments attaching the acromial process to the clavicle are damaged. Additionally, acromial impingement syndrome can develop if there is abnormal contact between the acromial process and the rotator cuff tendons.
