Cervical meninges, spinal cord and nerve roots dissected from behind
Cervical spinal cord and denticulate ligaments
The arachnoid membrane has been cut away to expose the cervical part of the spinal cord in situ. The small nodules located along the spinal roots of the accessory nerves (19) were identified microscopically as fibromata.

4 . Upper pointer: Posterior inferior cerebellar artery Lower pointer: Vertebral artery
5 . Suboccipital nerve
6 . Posterior arch of atlas (cut across)
7 . Dorsal roots cervical nerve II
8 . Obliquus capitis inferior muscle
9 . Greater occipital nerve
10 . Third occipital nerve
11 . Muscular branch of cervical nerve III
12 . Splenius capitis muscle
