The collateral eminence and hippocampus form the floor, which is separated from the hippocampus by a white matter layer called the alveus, whereas the roof is formed by the thalamus, the caudate nucleus, and tapetum. The stria terminalis forms the remainder of the roof, which is narrower than at the body, and the choroid plexus occupies the medial wall.

The lateral ventricles, similarly to other parts of the ventricular system of the brain, develop from the central canal of the neural tube. Specifically, the lateral ventricles originate from the portion of the tube that is present in the developing prosencephalon, and subsequently in the developing

During development, pressure from exterior structures causes a number of concave bulges to form within the lateral ventricles, which can be extremely variable in their degree of development; in some individuals they are ill-defined, while in others they can be prominent:

The tapetum for the temporal lobe comprises the lateral boundary of the inferior horn, on its way to join the main tapetum above the body of the ventricle (passing over the caudate nucleus as it does so). The majority of the inferior horn's floor is formed by the

Each lateral ventricle takes the form of an elongated curve, with an additional anterior-facing continuation emerging inferiorly from a point near the posterior end of the curve; the junction is known as the

The trigone of the lateral ventricle is the area where the part of the body forms a junction with the inferior horn and the posterior horn. This area is referred to as the
