Brain and spinal cord meninges are similar because <u>pia mater in both areas is made of the same tissue </u> They also have distinct differences including <u>dura mater in the two regions are made of different tissues.</u>
Meninges, the protective coverings of the central nervous system, come in two varieties: cranial and spinal.
The dura mater, arachnoid mater, and pia mater are the three connective tissue layers that make up most of their structure.
The fundamental distinction between cranial and spinal meninges is that, while spinal meninges are protective coverings for the spinal cord, cranial meninges are those for the brain, consisting of channels in the dura mater between various areas of the brain called Dural folds.
Additionally, the dura mater in the spinal meninges only has one layer, whereas the dura mater in the cranial meninges has two levels.
Furthermore, cranial meninges may not result in an epidural space while spinal meninges produce an epidural space filled with fat.
