The muscle located between your shoulder and neck is called the trapezius.
The trapezius is a large, triangular muscle that covers the upper back, shoulders, and neck. It plays a crucial role in various movements, including:
- Elevating the scapula (shrugging the shoulders): The upper fibers of the trapezius are primarily responsible for this action.
- Retracting the scapula (squeezing the shoulder blades together): The middle fibers of the trapezius contribute to this movement.
- Depressing the scapula (lowering the shoulders): The lower fibers of the trapezius are involved in depressing the scapula.
- Rotating the scapula: The trapezius assists in rotating the scapula, which is important for overhead movements.
- Extending the neck: The upper fibers of the trapezius can also help extend the neck.
The trapezius muscle originates from the spinous processes of C7-T12 vertebrae, the ligamentum nuchae, and the superior nuchal line of the occipital bone. It inserts onto the clavicle, acromion process, and spine of the scapula. This broad attachment allows it to influence movement and stability of the scapula, shoulder, and neck.
Common issues associated with the trapezius muscle include:
- Muscle pain and stiffness: This can be caused by poor posture, overuse, or stress.
- Trigger points: These are sensitive knots in the muscle that can cause referred pain to other areas of the body.
- Headaches: Trapezius muscle tension can contribute to tension headaches.
Proper posture, regular stretching, and strengthening exercises can help maintain the health and function of the trapezius muscle.
