Posterior view of a deep dissection of the suboccipital region of the neck showing the muscles of the suboccipital triangle: rectus capitis posterior major, obliquus capitis inferior, and obliquus capitis superior. The suboccipital venous plexus overlies these muscles. The greater occipital nerves can be seen emerging along the lower borders of the obliquus capitis inferior muscles before piercing the overlying semispinalis capitis muscles. (Image courtesy of AL Rhoton, Jr.)
