Overview

The trapezius — often called the "traps" — is a large, diamond-shaped muscle spanning the back of the neck, the shoulders and the upper spine. It has upper, middle and lower sections that pull in different directions.

Together these sections shrug the shoulders up, draw the shoulder blades together and steady them, and help support the neck and head. It gives the upper back and shoulders much of their shape.

Good to know

  • Helps position the shoulder blades for arm movement
