Flashcards in 07 Cerebrospinal Fluid Pathways Deck (16):
1

Set of four interconnected cavities in the brain, where CSF is produced and circulated

Ventricular system

2

Flowery-like plexus of ventricles within the brain

Choroid plexus

3

Found between ependymal tissue and also the subarachnoid space where the brain's blood supply is located

Pia mater

4

Ciliated epithelial cells lining the ventricular system of the brain and central of spinal cord

Ependymal tissue

5

Found through the ventricular system in the cerebrum down to the brain stem except the midbrain, the cerebral aqueduct at the narrowest point of the ventricular system

Choroid plexus

6

Choroid plexus secretes cerebrospinal fluid at ____

500 ml/day

7

Enlargement of the choroid plexus which provide larger spaces for the CSF in the lateral ventricle

Glomus

8

Aka arachnoid villi or Pacchionian bodies
Cauliflower-like protrusions of the arachnoid through the dura mater which absorb CSF into the cerebral veins
Found on the surfaces of the dural sinuses very close to the great veins

Arachnoid granulation

9

Largest part of the ventricular system follows the shape of the cerebral hemisphere
Has representative parts in the frontal, parietal, temporal and occipital lobes

Lateral ventricles

10

Most anterior portion, within the frontal lobe

Frontal horn

11

Within the frontal and parietal lobes, extends posteriorly to the region of the splenium of the corpus callosum

Body

12

Triangle/intersection part where the body, posterior and inferior horns meet

Trigone/atrium

13

Narrow and slit-shaped
Located in between the two thalami: formed by the hypothalamus and thalamus
Follows shape of basal ganglia

Third ventricle

14

Looks like a tent
Not a closed cavity unlike the lateral and third ventricles which only communicate with other parts of the ventricular system
Has 3 apertures through which the CSF can freely enter and exit and from subarachnoid space

Fourth ventricle

15

Median aperture

Foramen of Magendie

16

Lateral apertures

Foramina of Luschka
