Enlist the meninges of human brain.
✓
Answer
Meninges are the protective membranes surrounding the brain and spinal cord. They are as follows:
- Dura mater: It is the outermost tough, non-vascular, thick and fibrous meninx and is attached to the inner side of the cranium. Sub-dural space filled with serous fluid is present between dura mater and arachnoid mater.
- Arachnoid mater: It is the middle, thin and non-vascular layer of connective tissue having web like appearance. Sub-arachnoid space is present between arachnoid mater and pia mater. It is filled with Cerebrospinal fluid (CSF).
- Pia mater: It is the innermost delicate, highly vascular membrane. It lies in close contact with the CNS.
