Radial glia in the ectoneural neuroepithelium of the radial nerve cord in A. kochii. Transmission electron microscopy. a Low magnification view of the ectoneural neuroepithelium. b Intercelluar junctions between apicolateral surfaces of two adjacent radial glial cells. c Basal endfoot of a radial glial cell. d Attachment of the apical surface of a radial glial cell to the epineural cuticle. Abbreviations: bl – basal lamina; bp – basal process of a radial glial cell; c – epineural cuticle; ec – epineural canal; if – intermediate filaments; ne – neuropil; rg – radial glia.
