Q

What are the three layers of the meninges?

A

Dura mater
Arachnoid mater
Pia mater

19
Q

Describe the dura mater

A

Tough outer layer
Periosteum of skull
Closely associated with arachnoid

20
Q

Describe the arachnoid mater

A

Closely associated with the dura with projections down to pia mater.
Forms subarachnoid space where CSF flows

21
Q

Describe the pia mater

A

Shrink Wraps the brain and gives it a shiny appearance

22

25
Q

What links bones of the neurocranium?

A

Sutures

26
Q

What kind of joins are sutures?

A

FIbrous

27
Q

What are the two main sutures in the neurocranium?

A 
Coronal suture (frontal to parietals)
Sagittal suture (longitudinally to like parietals)
28
Q

Where do four bones join?

A

Pterion

29
Q

Which bones join at the pterion?

A

Frontal
Parietal
Temporal
Sphenoid

30
Q

Which artery runs deep to the pterion?

A

Middle meningeal artery

31
Q

What is a prominent feature of the arachnoid mater?

A

Arachnoid granulations- reabsorb CSF

32
Q

What do arachnoid granulations do?

A

Reabsorb CSF

33
Q

What two major structures does the dura mater form?

A

Tentorium cerebelli- separates cerebral hemispheres from cerebellum
Falx cerebri- Core of longitudinal fissure to separate cerebral hemispheres

34
Q

Where is CSF produced?

A

Lining of ventricles

35

How much CSF is produced daily?

A

400-500ml

37
Q

Describe the flow of CSF

A

Lateral ventricles -> 3rd ventricle -> 4th ventricle -> Central spinal canal (little) and subarachnoid space (most)

38
