Select the correct sequence of meninges from inside to outside
Durameter - Arachnoid mater - piamater
Arachnoid mater - Durameter - piamater
Piamater - Durameter - Arachnoid mater
Arachnoid mater - piamater - Durameter
As we have learnt:
-
Hence, the brain is surrounded by three membranes called meninges (sing-meninx).
Outer duramater is a tough white membrane present below the cranium, closely adhering to the cranium.
Middle arachnoid layer has a network of fibres.
Inner piamater is a thin, transparent, and vascular membrane close to the surface of the brain and spinal cord.
Hence, the correct answer is option a.
