Anterior and posterior longitudinal ligaments (more superior turns into tectorial membrane because needs to thin out) Nuchal ligament helps hold the head up but is more prominent in quadrapedal animals to stop head from falling forward (at back of neck through spinous process) Dens strapped to atlas anterior to posteriorly with the cruciform and alar ligament. Break these ligaments (whiplash) and brace base of skull do(cid:374)(cid:859)t have mechanical connection between spine and skull, stab brain stem (respiratory and cardiac centre) Uncinate processes develop throughout adult life and form uncovertebral joints, unique to vertebral joints, thought to be a result of too much or not enough neck movement.
