[The morphology of the cardia and the pylorus in the Chiroptera].
Organ complexes of bats (Nyctalis noctula), consisting of oesophagus, stomach and initial part of the small intestine have been subjected to histological and morphometrical investigation. As demonstrates the histological investigation of the preparations, the denticulate line of the mucous membrane of the oesophageal-gastric passage is displaced towards the stomach. In the cardia a well manifested internal sphincter has been revealed. In the place, where the stomach passes into the small intestine, on a small area of the submucosal tela of the intestine, there is an accumulation of secretory parts of the duodenal glands. They form a glandular torulus, which narrows the transitional zone lumen. A peculiarity of the bat pylorus is absence of an anatomical sphincter in it.
