Scanning electron microscopic study of the tongue in the owl (Strix uralensis)

The dorsal lingual surfaces of adult owl (Strix uralensis) were examined by scanning electron microscopy. The length of the tongue was about 2 cm. The tip of the tongue of the owl was bifid. Three parts were distinguished in the tongue of the owl: the apex, the body and the root of the tongue. The conical region between the lingual apex and lingual root was a very wide area. There were thread-shaped processes/cells of epithelium in the lingual apex. The small or large conical papillae were observed on the lingual body. The many openings of the lingual glands existed in the lingual body and lingual root.
