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.

Clinical significance
The volume of the lateral ventricles are known to increase with age. They are also enlarged in a number of neurological conditions and in patients with schizophrenia.[1]
Divisions
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
- the inferior or temporal horn into the temporal lobe
The body of the lateral ventricle is the central portion, just posterior to the frontal horn. The trigone of the lateral ventricle is a triangular area defined by the temporal horn inferiorly, the occipital horn posteriorly, and the body of the lateral ventricle anteriorly. The cella media is the central part of the lateral ventricle.
