title: Evidence of sensory neurons in the wall of the small intestine revealed by horseradish peroxidase technique.
abstract: Sensory neurons in the wall of the small intestine were studied by means of retrograde transport of horseradish peroxidase (HRP). After HRP injection into the mesenteric nerve trunks, peroxidase positive nerve cells were observed in the myenteric and submucous plexuses. Labeled cells of different shape and size were compared with neurones impregnated by silver nitrate. On the basis of HRP-labeled neurons it is concluded that some of the myenteric and submucous nerve cells send processes towards the celiac ganglia; these may correspond to afferent neurons in the wall of the small intestine.
