The septum pellucidum (Latin for "translucent wall") is a thin, triangular, vertical double membrane separating the anterior horns of the left and right lateral ventricles of the brain. It runs as a sheet from the corpus callosum down to the fornix. The septum is not present in the syndrome septo-optic dysplasia.
The cave of septum pellucidum (CSP), cavum septi pellucidi, or cavity of septum pellucidum is a slit-like space in the septum pellucidum that is present in fetuses but usually fuses during infancy. The septum pellucidum is a thin, laminated translucent vertical membrane in the midline of the brain separating the anterior horns of the right and ...
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 fornix. During the third month of fetal development, a space forms between two septal laminae, known as the cave of septum pellucidum (CSP), which is a marker for ...
The septal area refers to the nearby septum pellucidum. It is located underneath the corpus callosum and in front of the lamina terminalis . The lamina terminalis is a layer of gray matter that connects the optic chiasma and the anterior commissure . [ 7 ]
Septum Verum (true septum) is a region in the lower medial part of the telencephalon that separates the two cerebral hemispheres.. The human septum consists of two parts: the septum pellucidum (translucent septum), a thin membrane consisting of white matter and glial cells that separate the lateral ventricles, and the lower, precommisural septum verum, which consists of nuclei and grey matter.
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 septal veins drain blood from the septum pellucidum bilaterally [2] and terminate at the venous angle formed with the thalamostriate veins. [4] Research by Jonathan Roth et al., 2010, has shown that the septal veins are often asymmetrical. [5]
The lower edge of the septum pellucidum (the membrane that separates the lateral ventricles) is attached to the upper face of the fornix body. The body of the fornix travels anteriorly and divides again near the anterior commissure. The left and right parts separate, but there is also an anterior/posterior divergence.
