Abstract
Mucosal intra-epithelial nerve terminals have been found in the colon of the toad, Bufo marinus. Colocalized in the fibres are calcitonin gene-related peptide (CGRP)-like immunoreactivity (LI) and substance P (SP)-LI. The intraepithelial nerves are likely to be terminals of primary afferent sensory neurones. Fibres with vasoactive intestinal peptide (VIP)-LI or neuropeptide Y (NPY)-LI also supply the mucosa but do not penetrate the epithelium. © 1990.
