The longissimus cervicis muscle is the largest muscle on the anterior surface of the neck. It starts from the transverse processes of the upper cervical vertebrae and goes up and forward to the mastoid process. It is attached to the outer surface of the scapula and most often merges with the subclavian muscle and lies under the coracoid muscle. It is a powerful flexor muscle of the neck and body, as well as a rotator cuff muscle.
Purpose of the muscle The longissimus muscle is of great importance for the function of the entire body. It takes an active part in the movements of the head, neck, and torso, ensuring maximum mobility and maintaining balance of the body and head in static poses. It is included both in tonic tension during active movements, and in work during short-term tension when changing posture or external influence. Also, the neck longeicis plays the role of a shock-absorbing mechanism using tension to soften shocks and blows from the outside.
