Resumo: The present study had the purpose of analysing the morphological and quantitative characteristics of the neurons of the myenteric plexus of the stomach of rats. Samples of the stomach corpus were subjected to whole-mount preparations stained with NADH-diaphorase and to histological sections stained with Hematoxilin-Eosin. It was verified that, on the corpus of the stomach of rats, the muscular tunica shows two well defined layers, the circular and the longitudinal, while oblique fibers are rare. The neurons of the myenteric plexus are located between these two layers, which makes their evidencing easier in whole-mount preparations of this region. It was observed that near the small gastric curvature neuronal density is significantly larger than that near the large gastric curvature.

Amostras do corpo do estômago foram submetidas a preparados de membrana corados pelo método da NADH-diaforase e a cortes histológicos corados com Hematoxilina-Eosina. Verificou-se que, no corpo do estômago de ratos, a túnica muscular apresenta dois estratos bem definidos, o circular e o longitudinal, sendo raras as fibras com disposição oblíqua. Os neurônios do plexo mientérico localizam-se entre esses dois estratos, o que facilita a sua evidenciação, em preparados de membrana dessa região. Quanto à densidade neuronal, verificou-se que próximo à curvatura gástrica menor é significantemente maior que próximo à curvatura gástrica maior.Universidade Estadual De Maringá2008-07-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/448610.4025/actascibiolsci.v20i0.4486Acta Scientiarum.
