Labelling of individual ependymal areas in lateral ventricles of human brain: ependymal tables

Abstract

Different types of ependymal areas were studied and labelled in the human brain lateral ventricle. Periventricular structures were included in coining the names of the ependymal areas because they represent a basic and stable part of brain nerve structures suitable for the sake of clarity of localization of the ependyma. The labelling of individual ependymal areas was composed from letters: "Lv" (lateral ventricle); "E" (ependymal area) and letters for abbreviations of the closest periventricular structure, e.g. the septum pellucidum is "sp". The labelling for ependymal area over the septum pellucidum is thus "LvE-sp". The studied types of ependymal areas were arranged in so‑called ependymal tables for cornu anterius, pars centralis, cornu inferius and cornu posterius of the human lateral ventricle. Labelling of individual ependymal areas allows for better localization and characterisation of these areas in future studies carried out by various methods (e.g. morphological, biological, molecular) and will prevent from using misnomers with different types of ependymal areas in norm as well as in pathology (Tab. 5, Fig. 6, Ref. 22).

Value of Radiomic Analysis Combined With Diffusion Tensor Imaging in Early Diagnosis of HIV‐Associated Neurocognitive Disorders

“…36 The CP capillaries are fenestrated, and HIV-positive monocytes can pass from the blood into the CP and finally into the ventricles through the CP capillaries. 37 The CSF-brain barrier is an ependymal layer, which mainly consists of a single or multilayer array of columnar cells, 38 and the lack of tight junctions between the ependymal cells allows solute transfer between the CSF and parenchyma. Neurons whose axons or dendrites penetrate the ependymal layer and tanycytes found in the ependymal layer increase the possibility of contact between the CSF and subcortical nuclei.…”
