| Abstract | ||||
| This study utilized transmission electron microscopy (TEM) to examine the ultrastructure of the digestive system in the common kestrel (Falco tinnunculus), specifically focusing on various sections including the esophagus, proventriculus, and both small and large intestines, in relation to dietary adaptations. It was noted that the esophageal and large intestine mucosa predominantly contained a single type of epithelial cell. The proventricular cells' apex was distinguished by secretory granules, while the epithelial cells' apical region featured densely arranged, elongated microvilli. The small intestine's mucosa displayed diversity in epithelial cell types, including columnar epithelial cells, light and dark goblet cells, and Paneth cells. Goblet cells in the small intestine showed a striated border made of microvilli, mirroring those of columnar absorption cells, particularly evident in mature goblet cells prior to disruption by mucous mass expansion. In conclusion: The intricate structure of the kestrel's digestive tract and the specialized cellular makeup of its mucosal linings are intricately adapted to their specific digestive roles. | ||||
