Muscles Protecting the Scapula: Trapezius & Rhomboids

* Trapezius: This large, triangular muscle covers the back of the neck and shoulders. It helps to move the shoulder blades up and down, as well as rotate them.

* Rhomboids: These two small muscles are located between the shoulder blades. They help to pull the shoulder blades together and back, which helps to stabilize the shoulder joint.
