Answer 20

A couple of cavities within the brain responsible for the production, transport and removal of cerebrospinal fluid around the cranial cavity

Question 21

What is dura

Answer 21

One of the layers of CT that makes up the meninges of the brain

Question 22

Function of the dura

Answer 22

Limit rotational displacement of the brain

Question 23

What are the meninges

Answer 23

Three layers of membrane which work to protect the brain and the spinal cord from trauma with CSF

Answer 24

PIA
ARACHNOID
DURA

Question 25

List the different layers and locations of meninges

Answer 25

Delicate inner layer + PIA matter
