Verified step by step guidance

Understand the anatomy of the ventricular system in the brain, which includes interconnected cavities filled with cerebrospinal fluid (CSF). These cavities are the lateral ventricles, third ventricle, cerebral aqueduct, fourth ventricle, and central canal.

Recall that the cerebral aqueduct, also known as the aqueduct of Sylvius, is a narrow channel located in the midbrain. Its primary function is to transport CSF from the third ventricle to the fourth ventricle.

Visualize the flow of CSF: CSF is produced in the choroid plexus of the lateral ventricles, flows into the third ventricle via the interventricular foramen, and then passes through the cerebral aqueduct to reach the fourth ventricle.

Identify the fourth ventricle as the structure located between the brainstem (specifically the pons and medulla) and the cerebellum. It serves as the next destination for CSF after it passes through the cerebral aqueduct.

Recognize that the central canal is a continuation of the fourth ventricle, allowing CSF to flow into the spinal cord. However, the cerebral aqueduct does not directly connect to the central canal; it connects to the fourth ventricle first.
