The aim of this study was to the histological evaluation of the esophagus in 17-32 week old human fetuses. Material and Methods: 20 human fetuses whose ages ranged between 17-32 week-old and all of which were collected by University of Selcuk Meram Faculty of Medicine Department of Anatomy via spontaneous abortus under ethic rules were included in this study. The tissue samples of the esophagus were excised and processed with routine histologic methods, embedded in paraffin, stained with Hematoxylin-Eosin and evaluated light microscopically. Results: The histologic organization of the esophagus of the 17-20 week old fetuses was poor. However, the organization was accelerated after 21 weeks and almost finished after approximately 27 weeks. Conclusion: Fetal development of the esophagus accelerates after approximately 21 weeks and ending coarsely after 27 weeks.trinfo:eu-repo/semantics/openAccessEmbryonic DevelopmentEsophagusGastrointestinal SystemArticle274152157N/A
