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 cornu produced by the calcarine fissure. [ 2 ] It is sometimes visible on ultrasonogram [ 3 ] and can resemble a clot .
The interventricular foramina are two holes (Latin: foramen, pl. foramina) that connect the left and the right lateral ventricles to the third ventricle. [1]They are located on the underside near the midline of the lateral ventricles, [2] and join the third ventricle where its roof meets its anterior surface. [3]
[1] [2] The choroid plexus is a network of blood vessels present within sections of the four ventricles of the brain. It is present throughout the ventricular system except for the cerebral aqueduct, and the frontal and occipital horns of the lateral ventricles. [21] CSF is mostly produced by the lateral ventricles. [18]
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 ...
The lateral ventricles sit on either side of the septum. The septum pellucidum consists of two layers or laminae of both white and gray matter . [ 1 ] During fetal development, there is a space between the two laminae called the cave of septum pellucidum that, in ninety percent of cases, disappears during infancy.
CP, cortical plate; LV, lateral ventricle; MGE, medial ganglionic eminence. In vertebrates, the ventricular zone (VZ) is a transient embryonic layer of tissue containing neural stem cells, principally radial glial cells, of the central nervous system (CNS).
