Abstract

The myenteric plexus shows morphologic and quantitative variability in the alimentary canals of different species of animals. We have quantified and analyzed the morphology of the myenteric plexus of ten adult Cyprinus carpio intestinal bulbs, by means of histological cross sections stained with HE and Van Gieson methods, as well as Giemsa-stained whole mount preparations. The myenteric plexus, located between the longitudinal and circular layers of the muscular tunic, is formed by isolated neurons and ganglia. Percentages of small, medium and large neurons were 21%, 63.4% and 15.6%, respectively, with a prevalence of intermediary cytoplasmic basophily and peripheral nuclei. Neuronal density in 6.92mm² of intestinal bulb was of 2,040 neurons
