Question

multiple cholce question
what cavity is found within the midbrain?
the fourth ventricle
the lateral ventricle
the cerebral aqueduct
the interventricular foramen

Explanation:

To solve this, we recall the anatomy of the brain's cavities:

• The fourth ventricle is in the hindbrain (not midbrain).
• Lateral ventricles are in the cerebral hemispheres (not midbrain).
• The cerebral aqueduct (aqueduct of Sylvius) is a narrow canal in the midbrain, connecting the third and fourth ventricles.
• The interventricular foramen connects lateral ventricles to the third ventricle (not in midbrain).

Answer:

The cerebral aqueduct
