question 5
cerebrospinal fluid is formed by tissue in the walls and roofs of the:
a subdural space
b subarachnoid space
c ventricles of the brain
d fissure of sylvius
e dural sinuses

Explanation:

Cerebrospinal fluid (CSF) is produced by the choroid plexus. The choroid plexus is located in the ventricles of the brain. The subdural space is a potential space between the dura mater and arachnoid mater. The subarachnoid space contains the CSF but is not where it is formed. The fissure of Sylvius (lateral sulcus) is a groove on the brain's surface. Dural sinuses are venous channels in the dura mater.

Answer:

C. ventricles of the brain
