The lateral ventricles are two large, C-shaped cavities located within the brain. They are part of the ventricular system, which produces and contains cerebrospinal fluid (CSF). This fluid helps cushion the brain, remove waste, and provide nutrients. Each lateral ventricle is divided into several regions, including the anterior, posterior, and inferior horns. They are connected to the third ventricle through the interventricular foramen, allowing for the flow of CSF throughout the brain. The proper functioning of the lateral ventricles is essential for maintaining brain health and overall neurological function.
