facet
a small smooth flat surface on a bone
Atlanto- occiptal joint
the articulation between the head and c1 atlas flexion and extension
occipital
posterior inferior
occipital protuberance
center of occipital bone
nuchal line
ridge running horizontally along the back of head, from occipital protuberance to the mastoid processes
axial extension
cervical retraction
tuckin chin in involves head flexing on c1, with neck c2-c7 extending
