Fig. 5. Meshed model of parietal cell mitochondria reconstructed from a parietal cell cytoplasmic space of about 7 µmx4 µmx2 µm (lxwxh). Note that virtually every mitochondrion appears to be interconnected with an adjacent mitochondrion, either by major branching or via more diminished tight annular interconnections. Bar, 1 µm.
