Q2. Through which part of the brain does the cerebral aqueduct pass?
- Frontal lobe
- Medulla oblongata
- Cerebellum
- Midbrain
Q3. What normally flows through the cerebral aqueduct?

- Central canal
- Anterior horn of the lateral ventricle
- Fourth ventricle
Q6. Which ventricular cavity receives CSF directly from the cerebral aqueduct?

Q8. Why is the cerebral aqueduct particularly susceptible to causing obstructive hydrocephalus?
- It contains multiple large venous sinuses
- It has a narrow lumen
- It is the widest ventricular cavity
- It normally has no CSF flow

Q10. Which condition can result from blockage of the cerebral aqueduct?
- Peripheral neuropathy
- Obstructive hydrocephalus
- Epidural hematoma by definition
- Subdural hygroma only
