9

ranges of coupled motion among the typical cervical vertebrae will begin to decrease at what cervical vertebral couple?

C5/C6 vertebral couple

Rectus capitis anterior
Rectus capitis lateralis
Middle scalene
Levator scapula
Splenius cervicis
Obliquus capitis superior
Obliquus capitis inferior
Intertransversarii muscles

23

what is observed on the undersurface of the posterior arch of C1?

inferior vertebral notch and an attachment site for the posterior atlanto-axial ligament

24

what is the location of the zygapophysis relative to the atlanto-axial and atlanto-occipital intervertebral foramina?

it forms part of the anterior boundary of the intervertebral foramen in both cases

retrotransverse foramen

29

what are the possible contents of the retrotransverse foramen?

vertebral artery
branch from the suboccipital nerve
veins communicating with the venous sinuses of the neck
