Septum pellucidum
Septum Pellucidum
The Septum Pellucidum (pronounced sep-tum pel-lu-ci-dum) 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.
Etymology
The term "Septum Pellucidum" is derived from Latin, where "septum" means a partition or wall, and "pellucidum" means transparent or clear. This is in reference to the thin, almost transparent nature of this part of the brain.
Anatomy
The Septum Pellucidum is a thin, triangular, vertical double membrane in the brain that separates the anterior horns of the left and right lateral ventricles. It extends from the undersurface of the corpus callosum and is connected with the fornix below.
Function
The exact function of the Septum Pellucidum is not entirely understood. However, it is believed to play a role in the limbic system and is involved in the production of cerebrospinal fluid (CSF).
