The present study investigated the distribution of nerves in the oviduct of the sexually immature ostrich. The presence of protein gene product 9.5, neurofilament protein and neuron specific enolase nerve fibres were demonstrated in the infundibulum, magnum, isthmus, shell gland and vagina. Nerve fibres containing protein gene product 9.5, neuron specific enolase and neurofilament protein were particularly numerous in the tunica muscularis and intermuscular connective tissue areas of the shell gland and vagina. The presence of a large number of nerves in these oviductal regions is probably important in the coordination of muscle contraction. An interesting finding of the study was the presence of protein gene product 9.5 and neuron specific enolase immunopositive nerve fibres in the walls of blood vessels. It is likely that these nerves are autonomicin nature and play a role in the regulation of blood flow. This study has shown the presence of an extensive neural network in the oviduct of the ostrich. In addition, the results of the investigation have shown that the neuronal markers protein gene product 9.5, neurofilament protein and neuron specific enolase can be used to demonstate nerve fibres in the ostrich.

Posterior Glottis

It is well known that the protective laryngeal closure is elicited by mechanical or chemical stimulation of the epithelium in the glottis. In this study we used light microscopic observation and relative examination of the intraepithelial nerve fibers in the glottis to clarify the perceptive mechanism using immunohistochemical methods. In the anterior glottis, a moderate number of protein gene product 9.5-immunoreactive intraepithelial nerve fibers were observed, most of which were found to be located just anterior to the vocal process. The number of fibers in the upper surface of the vocal fold was larger than that in the free edge and the lower surface. Only a few calcitonin gene-related polypeptide-immunoreactive fibers were seen, and substance P-immunoreactive fibers were rarely seen. On the other hand, a dense distribution of protein gene product 9.5-immunoreactive nerve fibers was observed throughout the epithelium of the posterior glottis. The number of calcitonin gene-related peptide-immunoreactive fibers was about 20% that of protein gene product 9.5-immunoreactive fibers, whereas the number of substance P-immunoreactive fibers was only 1% to 2%. The results of this study suggest the possible existence of regional differences in the perceptive mechanism between the anterior and posterior glottis.
