Figure 1

Photomicrographs of retrogradely labeled motor neurons in the ventral horn (vh) of the sacral spinal cord following injections of CTB 488 (A, longitudinal section) or CTB 555 (B, C, transverse sections) into the ipsilateral foam gland. In A multiple injections were made into the gland, in B only a single injection in the gland was made, while in C as much of the gland as possible on one side was injected. Note in A the medial extension of dendrites at this ventral level of the cord. In contrast, note in B and C the very extensive dorsally directed dendrites that extend into the white matter and towards the medial aspect of the lateral funiculus (lf) and neck of the dorsal horn (dh). The asterisk denotes marginal, not dorsal root ganglion cells. Scale bar = 200 μm.
