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.
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.
