Does the Obliquus capitis inferior extend the atlas?

Where are the capitis and trapezius muscles located?
It lies deep to the semispinalis capitis and trapezius muscles. The muscle is responsible for rotation of the head and first cervical vertebra (atlanto-axial joint). It forms the lower boundary of the suboccipital triangle of the neck.
