The trapezius muscle, commonly known as the traps, is a large muscle in the upper back and neck region. It is responsible for movements like shrugging the shoulders and pulling the shoulder blades together.
The trapezius muscle in humans is a single, large muscle divided into three specific regions based on their functions: the upper trapezius, middle trapezius, and lower trapezius. Each region of the trapezius muscle contributes to different movements of the shoulder and neck.
The trapezius and sternocleidomastoid muscles are synergistic muscles, meaning they work together to perform certain movements. They both contribute to movements involving the head, neck, and shoulder region, such as turning the head or elevating the shoulders.
No, the trapezius is not inferior to the gluteus medius; in fact, it is superior. The trapezius muscle is located in the upper back and extends from the neck down to the middle of the back, while the gluteus medius is found in the hip region. Therefore, anatomically, the trapezius is positioned above the gluteus medius.
Trapezius Muscles (upper back)
The muscle that covers the back of the neck and upper middle region of the back is the trapezius. This large, triangular muscle extends from the base of the skull down to the middle of the back and out to the shoulders. It plays a crucial role in moving, rotating, and stabilizing the shoulder blades, as well as supporting the neck.

The scientific name for the 'neck' called the vertebrae.
The muscles around the spinous processes of C7 and T1-T5 primarily include the trapezius and the rhomboids. The trapezius muscle extends from the occipital bone down to the lower thoracic vertebrae and is responsible for stabilizing and moving the scapula. The rhomboid major and minor muscles, located between the scapula and the spine, aid in retracting and elevating the scapula. Additionally, the erector spinae group contributes to the movement and stabilization of the thoracic spine in this region.
The spine is bordered by several groups of muscles, including the intertransversarii muscle which facilitate movement between the individual vertabrae, and the multifidus spinae, which facilitate the movement of the spine as a whole. Other muscles in the back are associated with the movement of the neck and shoulders. The trapezius muscle, which is named from its trapezium-like shape, runs between the neck, the anterior chain, the two shoulders, and the thoracic vertebra, T12. The large latissimus dorsi make a triangle from the shoulder to the hip.
Trapezius - depends on actice region and stateof other muscles; may (1) elevate, retract, depress or rotate scapula upward, (2) elevate clavicle, or (3) extend neck
