Structure of the myenteric plexus in normal and diseased human ileum analyzed by X-ray virtual histology slices

Figure 2 Ganglion and fascicle from healthy human ileum. A: Within a portion of the ganglion, there is a neuron with an axon (thick arrow). Arrowheads indicate glial cells. Thin arrows indicate a single layer of telopodes at the border of the ganglion. The scale bar (50 µm) was applied to all subfigures; B: Part of a ganglion with several large (thick arrows) and medium-large (short thin arrow) neurons. The nuclei contain dark nucleoli. The cytoplasm is slightly granulated. Above the straight line, a small area of the neuropil was observed. Long thin arrows indicate the double-cell layer at the border; C: Normal nerve fascicle and thicker nerve with telopodes separating axons (arrows). Note the single layer of telopodes around the fascicle and nerve (arrowheads). Inset: Normal nerve fascicles stained with double immunohistochemistry. Telocytes run parallel to Schwann cells (light microscopy; S100: Schwann cells red; CD34: Telocytes brown).
