Question

what contains a spider web-like network of cells and fibers through which cerebrospinal fluid flows?
dural sinus
subdural space
pia mater
subarachnoid space
falx cerebri

Explanation:

The subarachnoid space is located between the arachnoid mater and the pia mater. It contains cerebrospinal fluid (CSF) and a spider - web - like network of cells and fibers called arachnoid trabeculae.

• Dural sinus: It is a venous channel that drains blood from the brain.
• Subdural space: A potential space between the dura mater and the arachnoid mater.
• Pia mater: The innermost meningeal layer that closely adheres to the brain and spinal cord.
• Falx cerebri: A fold of the dura mater that separates the two cerebral hemispheres.

subarachnoid space
