Similarities Between Brain and Spinal Cord Meninges
The similarities between brain and spinal cord meninges are:
- Meninges of both the brain and spinal cord consist of three layers: dura mater, arachnoid mater, and pia mater.
- Both meninges provides protection to the central nervous system and neural tissues.
- Subarachnoid space between the arachnoid mater and pia mater in both the meninges contains cerebrospinal fluid (CSF) that provides cushion to the neural structures.
- Blood vessels in both the meninges provides nutrients to the neural tissues.
Difference Between Brain and Spinal Cord Meninges
Meninges are the protective membranes surrounding and enclosing the brain and spinal cord. There are three layers of meninges: the dura mater, arachnoid mater, and pia mater. The main difference between brain and spinal cord meninges lies in the characteristic features of the dura mater. The brain’s dura mater has two layers: the periosteal and the meningeal layer. The spinal cord’s dura mater only has one layer, the meningeal layer. Brain and spinal cord meninges protect and support the central nervous system by containing cerebrospinal fluid and shielding against infections and injuries.
