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.
