What is the origin of the trapezius muscle?

The trapezius muscle has a broad origin that contributes to its extensive action in moving the scapula and supporting the shoulder girdle. Its origin is located on the spinous processes of the cervical vertebrae from C7 to T12, as well as the occipital bone at the base of the skull and the nuchal ligament, which runs along the back of the neck. This extensive attachment allows the trapezius to perform various actions, including elevation, retraction, and rotation of the scapula.

The other options do not encompass the full anatomical origin of the trapezius. For instance, while the spinous processes from C7 to T1 are part of its origin, they do not capture the complete span of the muscle, which also includes structures further down the spine and the nuchal ligament. Ribs and the inferior angle of the scapula do not relate to the trapezius's origin, highlighting the importance of understanding the anatomical framework of muscle origins for effective massage and therapy targeting.
