The distribution in the brainstem and cervical spinal cord of neurons supplying the reticulum and the reticular groove, the rumen, the omasum, the abomasum, and the small and large intestine was investigated in the sheep using the fluorescent retrograde tracer technique.

Abstract

The distribution in the brainstem and cervical spinal cord of neurons supplying the reticulum and the reticular groove, the rumen, the omasum, the abomasum, and the small and large intestine was investigated in the sheep using the fluorescent retrograde tracer technique. Only the reticulum and reticular groove were represented in the dorsal motor nucleus of the vagus nerve (DMNX), in the nucleus ambiguus (NA), and in the nucleus retroambigualis (NRA). The other forestomach, the abomasum and the small intestine were supplied by the DMNX only, with the exception of the rumen which was also innervated by the NRA. Some reticular formation neurons were found labeled after the injection of the tracer into the reticulum, the reticular groove, and the rumen. We present evidence that the reticular groove is the part of the forestomach having the widest representation, and also the richest innervation. © 2002 Elsevier Science B.V. All rights reserved.
