Raises the scapula at the Scapulothoracic Joint or inclines neck to corresponding side if the scapula is fixed
Levator scapulae
The levator scapulae muscle primarily elevates and rotates the scapula (shoulder blade) downward and inward, allowing for movements such as shrugging the shoulders. It can also contribute to lateral flexion of the neck when acting unilaterally.
The Rhomboids.
The rhomboid muscles and the middle trapezius muscle pull the scapulae medially. These muscles work together to retract and stabilize the scapulae toward the spine.
The most effective exercises for strengthening the levator scapulae muscle include shoulder shrugs, neck stretches, and scapular retraction exercises.
Trapezius and Levator Scapulae
levator scapulae
When the term "levator" is part of a muscle's action, it typically indicates that the muscle is involved in lifting or elevating a specific body part. For example, the levator scapulae muscle elevates the scapula (shoulder blade), while the levator anguli oris muscle elevates the angle of the mouth when smiling.
The muscle responsible for adducting the scapulae and helping to extend the neck is the trapezius. This large muscle spans the upper back and neck, and its upper fibers are particularly involved in neck extension and scapular adduction. When the trapezius contracts, it pulls the scapulae together while also allowing for neck extension.
Some effective exercises to strengthen and stretch the levator scapulae muscle include shoulder shrugs, neck stretches, and scapular retraction exercises. These movements can help improve the muscle's strength and flexibility, reducing tension and improving posture.
The synergist of the trapezius in scapular elevation is the levator scapulae muscle. It works together with the trapezius to elevate the scapula and assist in movements like shrugging the shoulders.
The serratus anterior is one, and the lower trapezius muscles are the others. The SA muscles pull the scapulae downward and anteriorly while the lower traps pull downward and medially.
