An example of trapezius function is an overhead press. When activating together, the upper and lower fibers also assist the middle fibers (along with other muscles such as the rhomboids) with scapular retraction/adduction. The trapezius also assists in abduction of the shoulder above 90 degrees by rotating the glenoid upward.
This is a compound exercise that also involves the trapezius, upper back, forearms, triceps, and the biceps. The narrower the grip the more the trapezius muscles are exercised. Upright rows are prone to injure the shoulder through internal rotation and elevation of the ball and socket joint.

The spinal component of the accessory nerve provides motor control of the sternocleidomastoid and trapezius muscles. [8] The trapezius muscle controls the action of shrugging the shoulders, and the sternocleidomastoid the action of turning the head. [8] Like most muscles, control of the trapezius muscle arises from the opposite side of the ...
The following outline is provided as an overview of and topical guide to human anatomy: . Human anatomy is the scientific study of the morphology of the adult human.It is subdivided into gross anatomy and microscopic anatomy.
The lifter stands erect, hands about shoulder width apart, and slowly raises the shoulders as high as possible, and then slowly lowers them, while not bending the elbows, or moving the body at all. [2] The lifter may not have as large a range of motion as in a normal shrug done for active flexibility. It is usually considered good form if the ...
The triangles of the neck describe the divisions created by the major muscles in the region.. The side of the neck presents a somewhat quadrilateral outline, limited, above, by the lower border of the body of the mandible, and an imaginary line extending from the angle of the mandible to the mastoid process; below, by the upper border of the clavicle; in front, by the middle line of the neck ...
Muscles in the Lateral compartment of leg also weakly participate, namely the Fibularis longus and Fibularis brevis muscles. Those in the lateral compartment only have weak participation in plantar flexion though. The range of motion for plantar flexion is usually indicated in the literature as 30° to 40°, but sometimes also 50°.
