Abstract

The dorsal lingual papillae of Sorex caecutiens were studied morphologically using scanning electron microscopy. Three types of lingual papillae were found: filiform papillae, fungiform papillae and circumvallate papillae. Filiform papillae were observed in most part of the tongue except on the lateral surface. There were basically three types of filiform papillae distinguished mainly by their morphological shape and structure. Numerous fungiform papillae were spread throughout the whole tongue, especially concentrated in lateral sides. The size varied according to the position of fungiform papillae, becoming larger as it reached to the rear. Strict pair-wise distribution was not observable, but fungiform papillae were mostly located in orderly manner. There were two large circumvallate papillae at the posterior region of the tongue. There were two thick pads around the center part where several bodies were gathered together. Overall research provided similar results with other close species such as common shrew (S. araneus). The circumvallate papillae of S. caecutiens were different from other Sorex species. They were circular, as in bats and other Sorex species, and had two distinguishable pads while others had only one.

뒤쥐(Sorex caecutiens) 혀유두의 형태적 특징을 알아보기 위해 주사전자현미경을 이용하여 관찰하였다. 혀유두는 실유두, 버섯유두 그리고 성곽유두의 세 가지 유형으로 관찰되었다. 실유두는 혀측면을 제외하고는 혀의 전역에 걸쳐 분포하고 있었으며, 형태와 구조적 특징을 기초로 하여 세 가지의 유형으로 구분되어졌다. 다수의 버섯유두는 혀 전체에 걸쳐 분포하였으며, 특히 혀의 양 측면에 걸쳐 존재하고 있었으며, 혀의 앞쪽보다는 뒤쪽으로 갈수록 크기가 더 컸었다. 버섯유두는 쌍을 이루며 분포하지는 않았지만, 대부분 일정하게 분포하였다. 큰 2개의 성곽유두는 혀의 후방부의 끝 가까이에 존재하고 있었다. 성곽유두는 바깥쪽(측면)이 두꺼운 두겹의 pad가 둥글게 둘러싸고 있었으며, 중앙에는 2개 혹은 3개 정도의 돌출된 둥글게 둘러싼 pad가 존재하고 있었다. 본 연구 종은 일반적인 뒤쥐류에서 볼 수 있는 혀의 형태와 거의 흡사한 구조를 가지고 있었음을 알 수가 있었다. 본 연구에서 성곽유두는 Sorex 종과는 차이가 있었다. 즉, 박쥐류와 Sorex 종에서와 같이 바깥쪽의 pad가 환상의 형태를 취하고 있다는 점에서는 동일하나 박쥐류와 Sorex 종의 경우는 바깥쪽의 pad가 한 겹인데 반해 본 연구 종은 두 겹의 환상 구조를 취하고 있다는 점에서 차이가 있었다.
