Question

Quizplus · Accepted Answer

The trapezius muscle is a large, triangular muscle that covers most of the upper back. It starts at the base of the skull and extends down to the middle of the back, and it is responsible for movements such as shoulder elevation, retraction, and depression. The rhomboid and infraspinatus muscles are located in the upper back as well, but they do not cover as much surface area as the trapezius muscle. The teres major muscle is located in the armpit area and is not part of the upper back musculature.
