The trapezius is largely involved in movements of the shoulder girdle, and is therefore functionally considered as a muscle of the upper limb rather than of the back. In this article, we will discuss the detailed anatomy and function of the trapezius muscle.
The trapezius is a muscle made up of particularly long muscle fibers that spanning a large width of the upper back. Functionally, this enables the trapezius to assist in mainly postural attributes, allowing and supporting the spinal column to remain erect when the person is standing.
What causes a trapezius muscle strain? Find out what you need to know about this problem with your upper back muscle, including how to treat it and how to prevent it.
The upper trapezius arises from your occipital bone in the back of your skull and the nuchal line in the back of your neck. The muscle also has attachments to the spinous processes of cervical levels one through six via the ligamentum nuchae.
The upper trapezius (G. trapeza, four-sided or four-legged table.) refers to the uppermost section fibers on the trapezoid-shaped muscle pair known as the trapezius.
Your trapezius muscles are two big muscles on either side of your upper back. They help you move your head, neck and upper back, and maintain and adjust your posture. Overuse, injuries and nerve damage are the most common causes of trapezius muscle pain.
The trapezius, trapezoid, or traps muscle is a muscle in the upper back. It stabilizes the shoulders and enables the neck to move. Certain stretches can help ease pain and keep movement...
Actions: Abduction of the upper limb at the shoulder (by rotating the scapula). The upper fibres of trapezius also elevate the scapula, the middle fibres retract, and the lower fibres depress. Innervation: Accessory nerve; Blood supply: Transverse cervical artery
The trapezius is a large muscle extending from the base of the neck down to the upper-middle back. It is a superficial muscle and an extrinsic muscle of the back. Still, it is considered an upper limb muscle instead of a back muscle because of its involvement in the movement of the shoulder girdle.
The trapezius is one of the major muscles of the back and is responsible for moving, rotating, and stabilizing the scapula (shoulder blade) and extending the head at the neck. It is a wide, flat, superficial muscle that covers most of the upper back and the posterior of the neck.
