In Plain English
The upper traps are the upper portion of the trapezius muscle, running from the base of the skull and neck to the collarbone and shoulder blade. They elevate your shoulders, help support the weight of your arms, and contribute to the prominent “yoke” that connects the neck and shoulders.
Technical Definition
The upper trapezius is the superior portion of the trapezius muscle, originating from the external occipital protuberance, superior nuchal line, ligamentum nuchae, and spinous process of C7 before inserting onto the lateral third of the clavicle and the acromion. Its primary actions include scapular elevation, upward rotation, and assistance with neck extension and lateral flexion, making it essential for shoulder girdle positioning and overhead arm movement.
