Final answer:
The fourth ventricle is continuous with the central canal of the spinal cord, situated at the brain stem and responsible for the flow of cerebrospinal fluid into the central canal.
Step-by-step explanation:
The ventricle that is continuous with the central canal of the spinal cord is the fourth ventricle. From the lateral ventricles, cerebrospinal fluid (CSF) flows through the third ventricle, then through the cerebral aqueduct, and finally into the fourth ventricle. The fourth ventricle is located at the brain stem, near the cerebellum and pons, and from there, CSF can continue down the central canal of the spinal cord.
The third ventricle is found within the diencephalon, and it is connected to the lateral ventricles by the interventricular foramina. After passing through the third ventricle, the CSF moves into the cerebral aqueduct and then into the fourth ventricle, where it is produced before flowing into the central canal of the spinal cord.
