The trapezius muscle is a large superficial back muscle that resembles a trapezoid. It extends from the external protuberance of the occipital bone to the lower thoracic vertebrae and laterally to the spine of the scapula. The trapezius has upper, middle, and lower groups of fibers. The ventral rami of C3 and C4 innervate the sensory functions of the trapezius. The spinal accessory nerve (cranial nerve XI) innervates the motor function of the trapezius. The function of the trapezius is to stabilize and move the scapula. The upper fibers can elevate and upwardly rotate the scapula and extend the neck. The middle fibers adduct (medially retract) the scapula. The lower fibers depress and aid the upper fibers in upwardly rotating the scapula. These motions allow for the scapula to rotate against the levator scapulae and the rhomboid muscles. This rotation, in conjunction with the deltoid muscle, is essential for throwing objects. Go to: Structure and Function The trapezius is a muscle comprised of particularly long muscle fibers spanning a large width of the upper back. Functionally, this allows the trapezius to assist in mainly postural attributes, allowing and supporting the spinal column to remain erect when the person is standing. The trapezius is one of the broadest and most superficial (closest to the skin) muscles of the upper back and trunk. It is often used as a landmark when dissecting a cadaver because it is encountered first. The trapezius is triangular, broad, and thin; it covers the upper back of the shoulders and neck. Its attachment points consist of the spinous process of C7-T12 of the spine, ligamentum nuchae, scapulae, clavicles, and ribs. While the trapezius muscle is mainly postural, it is also used for active movements such as side bending, rotation of the head, elevating and depressing the shoulders, and internally rotating the arm. The trapezius elevates, depresses, and retracts the scapula. The descending muscle fibers of the trapezius muscle internally rotate the arms. The transverse muscle fibers retract the scapulae, and the ascending muscle fibers medially rotate the scapulae. Thus, there are three components of the trapezius muscle.[1] The superior portion attaches to the skull (external occipital protuberance and superior nuchal line) and neck (ligamentum nuchae). This portion of the muscle extends the head at the neck. The middle portion attaches to the upper part of the spinous processes of C7-T12. This portion adducts (draws together) the two scapulae. The inferior portion (lower part of C7-T12) depresses the scapula. Muscular insertions are onto the scapular spine, acromion process, and the lateral third of the clavicle. The axio-appendicular muscles attach the body wall to the arm. The real significance of the functions of the muscles that attach the body wall to the scapula is that they fix the scapula so that the scapulohumeral muscles that attach the scapula to the arm can function effectively.[2] One way to visualize the actions of the back and upper limb muscles is to visualize a large construction crane. The giant arm is the most obvious feature of the crane, but the jacks that anchor the cab of the crane to the ground are essential to its stability. Without these muscles, the upper limb (the arm of the crane) would be useless. The unequal development of the three portions of the trapezius causes muscle imbalances and posture disturbances. Injury to the spinal accessory nerve (cranial nerve XI) can result in denervation and subsequent loss of motor function of the trapezius, resulting in muscle wasting (atrophy). Hypotonia and hyporeflexia are also characteristic of this lower motor neuron syndrome. The spinal accessory nerve (cranial nerve XI) and the trapezius can be examined during a clinical examination by asking the patient to shrug their shoulders passively and observe the shoulders for a shoulder droop. If pain occurs with passive stretching, this may be significant. Next, the examiner's hands are placed on the patient's shoulders while exerting downward pressure. The patient is then instructed to shrug the shoulders against this resistance allowing for assessment of any weakness. Unless strength against resistance is assessed, lesser degrees of muscle weakness may go unnoticed. The trapezius forms the posterior border of the posterior triangle of the neck. The sternocleidomastoid muscle (also innervated by the spinal accessory nerve) forms the anterior boundary. The clavicle completes the triangle.
