Following are the functions of the meninges:
-
Meninges are protective and nutritive.
-
The CSF in the meninges acts as the shock absorber and hence it protects the brain from mechanical injuries.
-
It maintains constant pressure inside cranium although changes in pressure and volume may occur in the blood of cranial vessels.
-
The CSF in the meninges helps in exchange of nutrients and wastes between blood and brain tissue.
-
It helps in the supply of oxygen to brain.
-
It protects the brain from desiccation.
-
The spinal cord has additional space outside the dura mater known as epidural space. It contains adipose tissue, which protects spinal cord from friction with vertebral column.
