Trapezius muscle

KNOW YOUR MUSCLES

The trapezius is one of the major muscles of the back and is responsible for moving, rotating, and stabilising the shoulder blade (scapula) and extending the head at the neck. It’s a wide, flat, muscle that covers most of the upper back and the back of the neck. Like most other muscles, there are two trapezius muscles – left and right – that are symmetrical and meet at the spine.
