Flashcards in Cerebrospinal Fluid Deck (14):
1

What secretes CSF?

Ependymal Cells that line the ventricular system

2

What is the Choroid Plexus?

A series of vapillary beds that extend into all four ventricles

3

True or False:

CSF continues as ventricular lining of the choroid plexus?

TRUE

4

Where is teh CSF produced and by what?

In the subarachnoid space by capillary beds in the meninges

5

At what rate is CSF continuously produced at per day?

500 ml/day

6

In general terms what does the CSF do?

Reduces the relative mass of the brain and also cushions it

7

Are their feedback mechnisms that can shut down CSF production?

NO

8

Why is the idea that CSF has no feedback mechanisms to stop production relative/important?

Because blockage of CSF flow can result in build up of interventricular pressure and/or intercranial pressure

9

What can cause blockage of interventricular pressure and/or intracanial pressure?

Build up of CSF 

10

What is Obstructive Hydrocephalus?

Blockage of normal flow of CSP out of the ventricular system

11

Where are the common locations Obstructive Hydrocephalus can occur?

1.) Interventricular foramen 

2.) Cerebral Aqueduct

3.) Outflow from the 4th ventricle

12

What is Communicating Hydrocephalus?

When CSF is blocked after it exits the ventricles, it is termed communicating because CSF can still flow between the ventricles

13

Distinguish between Obstructive hydrocephalus and Communicating hydrocephalus

Obstructive: results from blockage out of the ventricular system

 Communicating: results from absorbtion or circulation probelms
