From: Correlative cryo-electron microscopy reveals the structure of TNTs in neuronal cells
Schematic diagram depicting how cells connect via TNTs. TNT-connecting cells can either be single thick connections or a bundle of thin individual TNTs (iTNTs). iTNTs contain vesicles and mitochondria. Membranous compartments within iTNTs appear to be connected by thin filaments to actin on one side and to the inner side of the plasma membrane on the other. Thin membrane threads coil between and around several iTNTs. Cyan and magenta dashed squares show two types of contact sites: merging of iTNTs prior to fusion and fusion of iTNTs at separate locations, respectively
