Similarly, the term "tri-axle back plate" was historically used to describe the trapezius muscle. The superior or upper or descending fibers of the trapezius originate from the spinous process of C7, the external occipital protuberance , the medial third of the superior nuchal line of the occipital bone both in the back of the head , and the ligamentum nuchae. From this origin they proceed downward and laterally to be inserted into the posterior border of the lateral third of the clavicle.

The middle fibers, or transverse of the trapezius arise from the spinous process of the seventh cervical both in the back of the neck , and the spinous processes of the first, second, and third thoracic vertebrae. They are inserted into the medial margin of the acromion , and into the superior lip of the posterior border of the spine of the scapula. The inferior or lower or ascending fibers of the trapezius arise from the spinous processes of the remaining thoracic vertebrae T4—T From this origin they proceed upward and laterally to converge near the scapula and end in an aponeurosis , which glides over the smooth triangular surface on the medial end of the spine, to be inserted into a tubercle at the apex of this smooth triangular surface.

At its occipital origin, the trapezius is connected to the bone by a thin fibrous lamina, firmly adherent to the skin. The superficial and deep epimysia are continuous with an investing deep fascia that encircles the neck and also contains both sternocleidomastoid muscles. The rest of the muscle arises by numerous short tendinous fibers. It is possible to feel the muscles of the superior trapezius become active by holding a weight in one hand in front of the body and, with the other hand, touching the area between the shoulder and the neck.

Motor function is supplied by the accessory nerve. Contraction of the trapezius muscle can have two effects: movement of the scapulae when the spinal origins are stable, and movement of the spine when the scapulae are stable. The upper fibers elevate the scapulae, the middle fibers retract the scapulae, and the lower fibers depress the scapulae.

In addition to scapular translation, the trapezius induces scapular rotation. The upper and lower fibers tend to rotate the scapula around the sternoclavicular articulation so that the acromion and inferior angles move up and the medial border moves down upward rotation. The upper and lower fibers work in tandem with serratus anterior to upwardly rotate the scapulae, and work in opposition to the levator scapulae and the rhomboids , which effect downward rotation. An example of trapezius function is an overhead press. The trapezius also assists in abduction of the shoulder above 90 degrees by rotating the glenoid upward. Injury to cranial nerve XI will cause weakness in abducting the shoulder above 90 degrees. Dysfunction of the trapezius can result in winged scapula , sometimes further specified as "lateral winging" [6] and in an abnormal mobility or function of the scapula scapular dyskinesia.

Trapezius palsy , due to damage of the spinal accessory nerve , is characterized by difficulty with arm adduction and abduction , and associated with a drooping shoulder, and shoulder and neck pain. The trapezius muscle is one of the commonly affected muscles in facioscapulohumeral muscular dystrophy FSHD. The lower and middle fibers are affected initially, and the upper fibers are commonly spared until late in the disease. Although rare, underdevelopment or absence of the trapezius has been reported to correlate to neck pain and poor scapular control that are not responsive to physical therapy. It is mainly used in throwing, with the deltoid muscle and rotator cuff.

SA nerve is vulnerable to injury due to its superficial location in the subcutaneous tissue on the floor of the posterior cervical triangle. Other associated signs with SA nerve injury are scapular flip sign and scapular dyskinesia. A year-old volleyball player presented with difficulty in smashing the ball and excessive folds of shirt over right shoulder. He had undergone cervical lymph node biopsy three years back.

On examination, there was drooped right shoulder, wasting of trapezius with scapular hump, and extra-axillary fold [Figure 1a]. Scar mark of biopsy was seen in the posterior triangle of neck. The trapezius has three distinct heads: upper, middle, and lower. The upper fibers elevate, the middle fibers retract, and the lower fiber depresses the scapula. Trapezius is supplied by spinal accessory nerve SA which is most commonly injured after neck dissection or lymph node excision, penetrating injuries, compression by tumors.
