Where does trapezius originate?

Where does trapezius originate?

The trapezius has multiple origin and insertion points—it’s simply too big not to. It originates on the occipital bone, the ligamentum nuchae, and the spinous processes of T01–T12. The trapezius inserts on the lateral third of the clavicle, as well as the acromion and scapular spine of the scapula.

Where is the trapezius pars Spinalis located?

The trapezius muscle is a large, triangular, paired muscle located on the posterior aspect of the neck and thorax. When viewed together, this pair forms a diamond or trapezoid shape, hence its name. The trapezius has many attachment points, extending from the skull and vertebral column to the shoulder girdle.

What vertebrae does trapezius attach to?

Origin. The muscle attaches to the medial third of superior nuchal line; external occipital protruberance, nuchal ligament, and spinous processes of C7 – T12 vertebrae.

What is the trapezius muscle responsible for?

Since it is a muscle of the upper limb, the trapezius is not innervated by dorsal rami despite being placed superficially in the back. Contraction of the trapezius muscle can have two effects: movement of the scapulae when the spinal origins are stable, and movement of the spine when the scapulae are stable.
