Abstract: | The morphology of the digestive tract of three species of gerbils characterized by different food specialization—Rhombomys opimus, Meriones tamariscinus and M. meridianus—is considered. The correlation between areas of glandular and cornified epithelium is variable and depends greatly on the
type of stomach filling and distribution of food mass in it. The bordering fold and ileocecal junction is not only able to
isolate the forestomach and caecum significantly but also may be a mechanism of regulation of food movement through the digestive
tract. The close location of ileum’s opening to the caecum and its outlet to the colon, as well as isolation of caecum’s cavity
by a circular fold, could provide direct food transit from the ileum to the colon. |
