Which term refers to the muscle commonly known as the trapezius?

• A. Trapezius
• B. Ulna
• C. Tibia
• D. Synovial

Answer: (A)

Think of this in terms of names: a muscle vs a bone or a type of joint. The muscle that moves and stabilizes the shoulder girdle is named trapezius. It lies in the upper back and neck and helps elevate, retract, and rotate the scapula to lift the arm. The other options aren’t muscles: ulna is a forearm bone, tibia is a shin bone, and synovial describes joints with a synovial membrane and fluid. Since the question asks for the term that refers to the muscle commonly known as the trapezius, the correct term is trapezius.
