Question

Cerebrospinal fluid occurs

• A. Between arachnoid and duramater
• B. Beneath piamater
• C. Between arachnoid and piamater
• D. Between duramater and cranium

Answer 1

The correct option is C Between arachnoid and piamater

C. Between arachnoid metar and pia mater

Reason: CSF or cerebrospinal fluid is a clear, colorless body fluid found in the brain and spine. Subarachnoid space is a space between the arachnoid mater and the pia mater (inner layers of meninges). It is filled with CSF. It acts as a cushion for the brain's cortex by providing mechanical and immunological protection to the brain inside the skull. So the correct option is C.
