Lateral ventricles





The lateral ventricles are part of the ventricular system of the brain. Classified as part of the telencephalon, they are the largest of the ventricles. The lateral ventricles connect to the central third ventricle through the interventricular foramina of Monro.

Each lateral ventricle has three horns. The anterior or frontal horn extends into the frontal lobe, the posterior or occipital horn into the occipital lobe, and the inferior or temporal horn into the temporal lobe.
