1

what is the embryonic derivative of the apical ligament of the dens or the apicodental ligament

the notochord

2

what is the functin of the alar ligament

together they function to resist axial rotation

the membrana tectoria or tectorial membrane

4

what are the attachment sites for the superficial layer of the membrana tectoria or tectorial membrane

the posterior part of the inferior epiphyseal rim and vertebral body of C2 to the capsular ligament of the atlanto occipital joint and cranial dura of the posterior cranial fossa
