Describe the three meningeal layers that surround the central nervous system.
Expert Solution
Step 1
Meninges are membranous coverings of the spinal cord and the brain. These are three layers that protect the brain and spinal cord from any mechanical trauma. These layers also form a cavity through which the CSF (cerebrospinal fluid) passes and provide support to the blood vessels. On the basis of their location, meninges are known as spinal meninges (which cover the spinal cord) and cranial meninges (which cover the brain). However, the spinal and cranial meninges contain the same three layers and are continuous with each other.
