Conclusion – Difference between Brain and Spinal Cord Meninges
Brain and spinal cord meninges is a three layer membrane that protect and support the central nervous system. Both meninges produces cerebrospinal fluid in the arachnoid space and provides neural support. There are notable differences in the structure and function of the meninges of the brain and spinal cord. The main difference between the brain and spinal cord meninges is the dura mater. Brain meninges protects the brain in the brain in the cranial cavity and spinal cord meninges extend from the brainstem down to the filum terminale and protect the spinal cord in the vertebral column.
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.
