What is the action of the upper 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 (retract) the scapula. The lower fibers depress and aid the upper fibers in upwardly rotating the scapula.

Just so, what does the upper trapezius muscle do?

The trapezius muscle is a postural and active movement muscle, used to tilt and turn the head and neck, shrug, steady the shoulders, and twist the arms. The trapezius elevates, depresses, rotates, and retracts the scapula, or shoulder blade.

Likewise, what is the function of trapezius? Function. 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. Its main function is to stabilize and move the scapula.

Likewise, people ask, what is the action of the lower trapezius?

During progressive shoulder abduction (from 30 degrees to 120 degrees), the lower trapezius works to create upward rotation of the scapula (along with the serratus anterior). The lower trapezius muscle stabilises the scapula against the protraction effect produced by the serratus anterior.

Where is the upper trapezius muscle?

The trapezius is the most superficial (nearest to the skin) of the back, neck, and upper trunk muscles. This triangular muscle is broad and flat, lying just beneath the skin and covering the upper back of the shoulders and neck. It links to the dorsal vertebrae of the spine, scapulae, clavicles, and ribs.
