The frontal, occipital, and temporal horns of the lateral ventricles are joined together by which region?

The main idea is the junction point of the lateral ventricles’ horns. That central hub is the atrium, also called the trigone. It’s the region where the body of the lateral ventricle meets the posterior (occipital) horn and the inferior (temporal) horn. The frontal horn extends forward from the body toward the frontal lobe, so the atrium is the meeting point of the major horns. The other structures aren’t the junction: the foramen of Monro links the lateral ventricle to the third ventricle, the cavum septum pellucidum is a potential space between leaflets of the septum pellucidum, and the caudate head is a nearby neural structure, not the horn junction.
