The muscle that aids in drawing the head back and elevating the shoulder blades is known as the trapezius.
Trapezius Muscle:
The trapezius is a large muscle in your back. It forms a trapezoid shape at the back of your head and neck, continues across your shoulders, and to the center of your back.
The trapezius muscles also referred to as the "traps," are crucial for good posture. They protect the neck and spine, shift the shoulders, and lift the arms out to the sides. When you shrug or draw your shoulders back, we employ them.
Trapezius issues are uncommon but can happen. Any lesion to the cranial nerve XI, the spinal accessory nerve, can weaken or paralyze the trapezius muscle. Trapezius muscle tension occurs when the trapezius muscle is overextended. The muscle may rip under some circumstances.
