Cervical meninges, spinal cord and nerve roots dissected from behind
Dura mater in cervical region and in posterior cranial fossa
The dura has been cut away so that the transparent arachnoid membrane is exposed. The subarachnoid space increases in volume above the level of the second cervical dorsal roots forming part of the cerebellomedullary cistern (cisterna magna).

  2. Mastoid emissary vein
  3. Dura mater
  4. Occipital artery
  5. Superior oblique capitis muscle
  6. Left vertebral artery
  7. Posterior arch of atlas (cut across)
  8. Inferior oblique capitis muscle
  9. Greater occipital nerve
  10. Arch of axis (cut across)
  11. Dura mater
  12. Splenius capitis muscle
  13. Nerve to semispinalis capitis muscle
  14. Posterior external vertebral venous plexus
