Which Layer of the Meninges is delicate, lines the Dura, and is weblike in appearance?

Back 21

The Arachnoid Space

Front 22

The sub arachnoid space is between what layers of the meninges?

Back 22

The Subarachnoid space is under the Arachnoid Mater, and above the Pia Mater.

Front 23

What space contains Cerebrospinal Fluid?

Back 23

Subarachnoid Space

Front 24

Front 26

What is the purpose of the Ventricles and the Choroid Plexus?

Back 26

To produce cerebraospinal fluid for the subarachnoid space.

a. Lateral Ventricle
b. Third Ventricle
c. Fourth Ventricle
d. B & C
e. All of the Above

Back 29

E. The choroid plexus is located in ALL ventricles therefore all ventricles produce CSF (Cerebrospinal Fluid)

Front 31

Where does Cerebrospinal Fluid go after it has surrounded the brain?

Back 31

It exits via the ARACHNOID VILLI into the SUPERIOR SAGITTAL SINUS it opens valves to the superior sagittal sinus when the pressure is high enough. Cerebral Spinal Fluid can flow into blood. The valves do not allow blood IN.
