The main difference between cranial and spinal meninges is that cranial meninges are the protective coverings of the brain, consisting of channels in the dura mater between various parts of the brain called dural folds, whereas spinal meninges are the protective coverings of the spinal cord whose dura mater acts as a dural sheath. Distally, the meninges form a strand of fibrous tissue, the filum terminale, which attaches to the vertebral bodies of the coccyx. What are the two layers of the dura mater within the skull?
