Lateral ventricles and horns The lateral ventricles connected to the third ventricle by the interventricular foramina. 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 trigone of the lateral ventricle.
The ventricles contained within the rhombencephalon become the fourth ventricle, and the ventricles contained within the mesencephalon become the aqueduct of Sylvius. Separating the anterior horns of the lateral ventricles is the septum pellucidum : a thin, triangular, vertical membrane which runs as a sheet from the corpus callosum down to the ...
The calcar avis, (calcarine spur) previously known as the hippocampus minor, [1] is an involution of the wall of the lateral ventricle's posterior horn produced by the calcarine fissure. [2] It is sometimes visible on ultrasound [3] and can resemble a clot. [4]

In the lateral ventricles, it is found in the body, and continued in an enlarged amount in the atrium. There is no choroid plexus in the anterior horn . In the third ventricle , there is a small amount in the roof that is continuous with that in the body, via the interventricular foramina , the channels that connect the lateral ventricles with ...
Posterior horn of lateral ventricle in the brain, which passes forward, laterally and slightly downward, from the corpus callosum into the occipital lobe Posterior horn of spinal cord , the dorsal (towards the back) grey matter section of the spinal cord that receives several types of sensory information from the body including light touch ...
Coronal section of inferior horn of lateral ventricle. Fimbria labeled at center left and alveus to the right. Fimbria-fornix fibers are the hippocampal and subicular gateway to and from subcortical brain regions. [13] [14] Different parts of this system are given different names:
