Question

unit 4 - challenge 4.2: the anatomy of the nervo
which of the following is the layer of the cranial and spinal meninges that
contains cerebrospinal fluid (csf)?
a.) arachnoid mater
b.) pia mater
c.) dura mater
d.) subarachnoid space

Explanation:

The subarachnoid space is the layer between the arachnoid mater and pia mater. It is the specific location where cerebrospinal fluid (CSF) is contained. The arachnoid mater (a) is a membrane, the pia mater (b) is a delicate inner - most membrane, and the dura mater (c) is the tough outer - most membrane. None of these membranes themselves contain the CSF; it is the subarachnoid space (d) that holds the CSF.

Answer:

d. Subarachnoid Space
