Front 21

Meninges

Back 21

The layer of membranes that cover the central nervous system (CNS) and the peripheral nerves. Chapter 2.

Front 22

Dura Mater

Back 22

The outermost of the three layers of meninges; found in both the central nervous system (CNS) and the peripheral nervous system (PNS). Chapter 2.

Back 24

The innermost the layers of the layers of meninges, found in both the CNS and the PNS. Chapter 2.

Front 25

Subarachnoid Space

Back 25

A space filled with cerebrospineen the fluid (CSF) that lies between the arachnoid and pia mater layers of the meninges in the CSN. Chapter 2.

Front 26

Cerebrospinal Fluid (CSF)

Back 26

Front 29

Central Canal

Back 29

The small midline channel in the spinal cord that contains CSF.
