Figure 8

The tibial neuron in semi-thin sections. A-E show examples from a series of consecutive semi-thin sections starting at the soma A close to the retractor unguis motor nerve and proceeding further distal (the arabic numerals on the right give the section number). The soma is surrounded by a thick glial capsule (g, dark blue staining) that decreases in thickness in distal regions D, E. Distally the cytoplasm is invaded by glial tendrils (arrowheads) and contains areas that in the electron microscope look like bundles of small dendrites surrounded by glial processes (x, y, z; compare Figure 9) Scale: 20 μm.
