Along with the structures known as the third ventricle and the fourth ventricle, the lateral ventricles are part of the body's ventricular system.he separate sections of the ventricular system are connected through small holes known as foramina. The lateral and third ventricles connect through the right and left interventricular foramina, while the third and fourth ventricles connect through a foramen known as the cerebral aqueduct.
In front, the third ventricle communicates with the lateral ventricles, and in back it communicates with the aqueduct of the midbrain (the aqueduct of Sylvius). The fourth ventricle is the most inferior of the four ventricles of the brain. It extends from the aqueduct of the midbrain to the central canal of the upper end of the spinal cord, with which it communicates by the two foramina (openings) of Luschka and the foramen of Magendie.
