  Muscles of the Pectoral, Back and Shoulder Regions
The muscles of the shoulder are divided into three groups: (1) the superficial extrinsic muscles (trapezius and latissimus dorsi); (2) the deep extrinsic muscles (levator scapulae, rhomboids, and serratus anterior); and (3) the intrinsic muscles (deltoid, supraspinous, infraspinous, teres minor, teres major, and subscapularis).
The trapezius muscle attaches the pectoral girdle to the skull and the vertebral column and assists in suspending it.
This is large, wide, fan-shaped muscle passes between the trunk and the humerus and acts on the shoulder joint and indirectly on the pectoral girdle.

For each muscle examined throughout the course, the following characteristics should be observed: origin, insertion, nerve supply, blood supply (arteries and veins), parts and structural arrangement of the muscle, and its relationships (position in the body and its relation to other structures adjacent to it) and a consideration of its action.
On the deep surface of a muscle, near the junction of its proximal and middle thirds, is usually the entrance of the artery, vein, and nerve (neurovascular bundle).
Distinguish between the accessory nerve (Cranial Nerve XI) (reaching the muscle from the posterior triangle of the neck along the deep surface of the superior border of the muscle) and branches of cervical nerves 3 and 4 (C3, 4) reaching the muscle from a position anterior and deep to the levator scapulae muscle.

The biarticulate levator scapulae enters passive insufficiency through the completion of scapula depression and upward rotation when the neck is laterally flexed and rotated to the opposite side or through the completion of neck lateral flexion and rotation when the opposite scapula is depressed and rotated upward.
The biarticulate levator scapulae enters active insufficiency through the completion of scapula elevation and downward rotation when the neck is laterally flexed and rotated to the same side or through the completion of neck lateral flexion and rotation when the scapula is elevated and rotated downward to the same side.

On two subsequent occasions, I injected the secondary trigger points (in the bicipital groove and the scapular insertion of the levator scapulae superioris muscle), the muscle belly of the brachioradialis (at the left elbow), and the trigger point in the temporalis muscle in a similar manner.
The inferior belly of the patient's omohyoideus muscle was extremely tender to palpation, and the brachial plexus was slightly tender.
She also experienced intense spasm of the levator scapulae superioris on the right side, and she had aching in her jaw, temporalis area headache, and burning in the inner upper aspect of the right scapula.

It is supported and stabilized by five muscles on each side of the body, the trapezius, the rhomboid muscles, the levator scapulae, the pectoralis minor, and the serratus anterior.
The serratus anterior muscle takes origin from a broad area on the front of the chest, runs laterally around the rib cage, passes underneath the scapula to insert on its medial border, and acts to abduct it, that is, to pull it laterally.
The rhomboid muscles adduct the scapula, pulling its medial border toward the midline from its origin on the thoracic spine, and the levator scapulae elevates the scapula, as its name implies, pulling on its upper border from an origin on the transverse processes of C1–4.

 BioMed Central | Full text | Does preoperative abduction value affect functional outcome of combined muscle transfer ...
Subscapularis muscle was released from the anterior surface of the scapula subperiostally from a small incision at the lateral side of the scapula carefuly, in order to prevent injury to the pedicle of lattisimus dorsi and teres major muscles (Figure 6).
In that condition, the levator scapulae muscle is utilised as an intrinsic stabilizer of glenohumeral joint and trapezius muscle is used as a prime mover for shoulder abduction with or without latissimus dorsi and teres major transfers [9].
Extensive dissection of latissimus dorsi and teres major muscles from the surrounding structures gave us the opportunity to utilize both muscles for transfer, without any difficulty during the passage of the conjoined tendon through the tunnel which was prepared between long head of triceps and deltoid muscle, and also during reinsertion to the humerus.

Considerable controversy exists as to the constancy of a bursa in connection with the levator scapulae, which may be inserted in two layers enfolding the medial border of the scapula, and a second bursa found in the areolar tissue between the two layers.

The region involved is somewhat lateral to the medial superior scapula border (at least 3-4 finger breadths in a normal sized individual) (Figure 7), so the tender area is clearly differentiated from the medial angle of the scapula where the levator scapulae muscle inserts in the scapulocostal syndrome.

To this day, I find that Counterstrain is a favourite of mine for the levator scapulae, simply because so many people have pain in the trigger points or at the attachment of the muscle to the scapula.
