What is the acromion process?

The process of acromions, also known as Acromion, is the bony structure on the upper part of the shoulder blade or shoulder blade. It results from the ridge that passes horizontally the upper part of the shoulder on the back and protrudes at the top of the shoulder and forms a club shape. In conjunction with the Coracoid process, similar to a protrusion in the shape of a club that arises from the front of the shoulder blade and crosses laterally towards the shoulder joint. The Acromion process serves as a connection point for deltooid and trapezoid muscles. Its superior or upper surface is convex and rough, fishing up and upwards above the shoulder joint, while its inferior or lower surface is concave and smooth.

One of the functions of the acromion process is to connect with the keyboard to form an acromioclavicular (AC) joint. Here, the collarbones with a flattened side end meet the middle or inner boundary of the acromion and create a type of synovial joint known as a sliding joint. In the Glidinug joint, adjacent bone surfaces slide around him. As the joint surfaces of the collarbones andThe acromions slide against each other, allowing the arm to lift over their heads.

Another purpose of the acromion process is to act as a place of muscle connection. On the arm of the middle deltooid fibers come on the side edge of the acromion, crossed the shoulder joint and put into the deltoid tuberosity partly down from the outside of the upper arm. The main function of the deltooid muscle, especially its middle fibers, is the abolition of the arm or lifts it laterally away from the body. This action occurs on Glenohumeral or shoulder, joint, but the connection of muscle to acromion provides a lever effect that helps lift the weight of the arm.

Trapezius muscle of the upper back, especially its center, also connect to the acromion process. The middle trapezoid comes from spinning processes of the thoracic vertebrae and passes the upper back horizontally and inserts into the middle edge of the acromion. The function of the middle fibers of the trapezoid is againUnit the shoulder blades, pull them back and together. This in turn pulls the arms back to the shoulder joint, the movement that begins between the shoulder blades and ends in the movement of the shoulders.
