Small Posterior of the Head (M. Posterior Minor)

A deep neck muscle, responsible for pulling the neck back and rotating the head. Its origin is at the back of the first cervical vertebra and attaches to the bottom line of the occipital bone.

Large Posterior of the Head (M. Posterior Major)

A large, deep neck muscle responsible for head extension and rotating the head. Its origin is the second cervical vertebra and attaches to the bottom line of the occipital bone, just beside the Small Posterior.

Large Oblique (M. Obliquus Inferior)

A deep neck muscle responsible for head extension. It originates at the second cervical vertebra and connects to the side of the first cervical vertebra.

Small Inferior Oblique (M. Obliquus Superior)

A deep neck muscle that helps extend the head. This small muscle originates at the side of the first cervical vertebra and attaches to the space between the two lines at the back of the skull.
