Ventricular System of the Brain
👩⚕️ For this lesson, again just practice drawing the diagram until you've memorised it. You can look on Google Images of YouTube to get a better idea but it's easier to memorise using a simplified diagram like this.
Ventricular system of the brain
CSF flow pathway:
Lateral ventricles ➡️ Foramen of Monro ➡️ Third ventricle ➡️ Aqueduct of Sylvius ➡️ Fourth ventricle ➡️ Foramen of Magendie (median) / Foramen of Luschka (lateral) ➡️ Subarachnoid space
Where is the most common site of obstruction in hydrocephalus?
Cerebral aqueduct of Sylvius
The Cerebral aqueduct of Sylvius is the narrowest part, making it the most frequent site of obstruction (aqueductal stenosis).
