Abstract

The study aimed to reveal the similarities and differences of the tongue of the merlin with other bird species. Merlin is the smallest bird of the Falconidae family and lives in America, the northern regions of Europe and Asia, the Middle East, and Central Asia. Since these species don’t have teeth, lips, and cheeks, the tongue fulfills significant functions related to nutrition, and it differs morphologically as a result of differences in eating habits. In this study, the tongues obtained from five adult merlin (falco columbarius) were examined by morphological and stereological methods. It was determined that the tongue of the merlin was thin, long, and rectangular, the front part was oval, W-shaped papilla linguales caudales were found between the body and root of the tongue. The average length of the tongue was 26.32 ± 1.38 mm, the width was 7.26 ± 0.32 mm, and the thickness was 1.58 ± 0.14 mm. The histology of the tongue showed that the dorsal and ventral surfaces are covered with keratinized multilayered squamous epithelium; there are taste buds in the epithelial layer, the number of taste buds is higher especially on the root of the tongue; and the presence of paraglossum, which is in the hyaline cartilage structure. The volume of the tongue was on an average of 374.2 ± 14.08 mm3.

Bozdoğan Dilinin Makroanatomik ve Stereolojik Olarak İncelenmesi

Abstract

Bozdoğan, doğangiller (Falconidae) familyasının en küçük kuş türü olup Amerika, Avrupa ve Asya’nın kuzey bölgelerinde, Ortadoğu ve Orta Asya’da yaşar. Kanatlılarda diş, dudak ve yanak gibi organlar bulunmadığından dil beslenme ile ilgili önemli fonksiyonları yerine getirmektedir. Beslenme alışkanlıklarındaki farklılıklar sonucunda morfolojik olarak oldukça farklılık göstermektedir. Bu çalışmamızda beş adet ergin bozdoğandan (falco columbarius) elde edilen diller morfolojik ve stereolojik olarak incelenmiştir. Morfolojik incelemelerimiz sonucu bozdoğan dilinin ince, uzun ve dikdörtgen şeklinde, ön kısmının oval olduğu, corpus linquae'sı ile radix linguae’sı arasında papilla linguales caudales’lerin bulunduğu tespit edildi. Ölçümlerimiz sonucunda ise dilin uzunluğunun ortalama 26,32 ± 1,38 mm, eninin ortalama 7,26 ± 0,32 mm, kalınlığının ise 1,58 ± 0,14 mm olduğu saptandı. Histolojik incelemelerimizde bozdoğan dilinin dorsal ve ventral yüzeyinin keratinize çok katlı yassı epitel ile kaplı olduğu, epitel katman içerisinde özellikle radix lingua tarafında sayısı artan biçimde tat tomurcukları bulunduğu ve dil dokusu içerisinde sağlı sollu bulunan ve hyalin kıkırdak yapısında olan paraglossum’un varlığı saptandı. Dilin stereolojik olarak hesapladığımız hacmi ise ortalama 374.2 ± 14.08 mm3 olarak tespit edilmiştir.
