Flashcards in Hydrocephalus Deck (22):
1

A build-up of CSF on the brain in the ventricles or cavities

Hydrocephalus

2

Non-obstructive hydrocephalus

communicating hydrocephalus

3

Obstructive hydrocephalus

non-communicating

4

Block at the foramen of Monro

lateral ventricles, but not in third and fourth ventricles

5

block at cerebral aqueduct

lateral ventricles and third ventricle but not in the fourth ventricle

6

block at foramina of Luschka and Magendie

congenital malformation of the brain in which the cerebellum is lodged in the foramen magnus and causes hydrocephalus in ALL ventricles

7

block in the arachnoid vili

all of the ventricles are in communication with on another, but CSF is simply not being resorbed back into venous system "communicating hydrocephalus"

8

What is responsible for the formation of CSF?

chorid plexus

9

Obstruction of cerebral aqueduct would cause hydrocephalus in which ventricles?

lateral and third ventricles

10

What do Schwann cells to?

myelination of the peripheral nervous system

11

function of astrocytes

maintain extracellular ionic environment

12

qeiuscent cells that become activated after CNS damage

microgalial

13

oligodendroglial cells

cells types that make up the myelin of the CNS

14

The inferior horn of the lateral ventricles are found within what lobe?

the temporal lobe

15

What lobe is the body of the lateral ventricles found?

parietal

16

The posterior horn of the lateral ventricle is located in what lobe?

occipital

17

What portion of the lateral ventricles are located in the frontal lobe?

anterior portion of ventricle

18

cerebral aqueduct is associated with

the midbrain

19

Define superior sagittal sinus

a venous structure into which the CSF of the subarachnoid space flows

20

The third ventricle is associated with what?

thalamus/hypothalamus

21

What is the fourth ventricle associated with ?

the medulla

22

how does CSF enter the third ventricle?

via two foramen of monro
