Lateral Ventricles - Divisions

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. Ependyma cover the inside of the lateral ventricles and are epithelial cells.
