|
What are the parts of the lateral ventricle and importance of each structure
|
- Frontal horn~ no choroid, good for shunting
- Body~ contains choroid in floor - Trigone~ glomus - Occipital/Posterior~ no choroid - Temporal/Trigone~ choroid in superior-medial aspect |
|
|
Importance of the Interventricular Foramen (of Monro)
|
- connects the 2 lateral ventricles to the 1 3rd ventricle and choroid plexus travels through
|
|
|
Importance of the 3rd ventricle
|
- roof formed by the tela choroidea (has internal cerebral veins and choroid plexus)
|
|
|
Importance of the Cerebral Aqueduct (of Sylvius)
|
connects 3rd and 4th ventricle
|
|
|
Importance of the 4th ventricle
|
- contains choroid plexus in inferior medullary velum that's continuous with the lateral aperture (foramina of Luschka) but not the medial aperture (foramenn of Magendie)
|
|
|
Subarachnoid space/cisterns/Arachnoid granulations
|
- CSF travels in these areas across cerebrum/cerebellum convexities and is reabsorbed by arachnoid granulations
|
|
|
Obstructive Hydrocephalus
|
- block in part of the ventricular system so the area prior is enlarged (ie stenosis of cerebral aqueduct)
|
|
|
Communicating Hydrocephalus
|
- blockage in cisterns/ arachnoid granulations/ subarachnoid space
|
