Roof of the epineural canal (epineural epithelium) in A. kochii. Transmission electron microscopy. a Flattened glial cell (gc) of the epineural epithelium. b Hemidesmosomes (arrowheads) anchoring a glial cell of the epineural epithelium to the basal lamina (bl) and to the epineural cuticle (c). c The epineural epithelium occasionally contains basiepithelial neural processes (np), but not neuronal perikarya. Abbreviations: bl – basal lamina; c – epineural cuticle; ec – epineural canal; gc – flattened glial cell; if – intermediate filaments; ne – ectoneural neuroepithelium; np – neuronal processes
