“…Human brain atlases describe 30-35 periventricular structures bordering the third ventricle (19,20). In our previous study, we used 15 periventricular structures to designate individual ependymal areas of the third ventricle (21). With the help of SEM, we examined the apical surface of 6 defi ned areas, each of which was examined in 3 brains of different patients.…”

OBJECTIVES: The ependymal lining of the human brain ventricular system displays distinct structural differences and functional heterogeneity among individual ependymal cells (ECs). To date, multi-ciliated ECs (E1 cells), bi-ciliated ECs (E2 cells), uni-ciliated ECs (E3 cells), ECs without cilia, and ECs with cytoplasmic protrusions have been described in human brain ventricles. METHOD: Using scanning electron microscopy (SEM), we evaluated ependymal samples from 6 defi ned regions of the third ventricle from 9 human brains. These regions were strictly defi ned according to the periventricular structures they neighbour with. RESULTS: We observed different structures on the apical surface of the ECs. Various ECs differed from each other by the presence of microvilli, secretory bodies, and a variable number of cilia, which led us to divide the ECs into several exactly specifi ed types according to their apical morphology. CONCLUSION: We found all types of ECs in every examined region with a predominance of particular types of apical surface of ECs in the individual areas (Tab. 4, Fig. 7, Ref. 22).
