Abstract in English
The present study aimed to compare the epithelium tissue of mucosa layer of
gastrointestinal tract in three types of lower vertebrates: Scyliorhinus canicula, Sparus
aurata, Salamandra infraimmaculata. The results of the histological and comparative
study showed that the majority of digestion system parts were lined with simple
epithelium tissue while others were lined by pseudostratified epithelium tissue. Goblet
cells were distributed in all studied parts of digestion systems with density in some
locations. Esophagus was characterized by ciliated epithelium tissue, and the tubular
glands were presents in the stomach mucosa. Concerning the Lumina properia, it was
visible in all digestive system parts with some differences according to the animal species
studied.
