| 摘 要： | 目的]揭示甘肃鼢鼠的听觉特征。方法]利用电生理学方法,对甘肃鼢鼠耳蜗的显微结构进行分析。结果]扫描电镜结果表明,外毛细胞静纤毛的长度靠近耳蜗轴最短,靠近耳蜗侧壁最长,由蜗底到蜗顶逐渐变长,静纤毛的数目由蜗底到顶逐渐减少。耳蜗蜗顶外毛细胞和静纤毛常排列不规则,而且可见少数静纤毛自然缺失。内毛细胞和静纤毛一直排列到耳蜗顶盲端,毛细胞和静纤毛数目均未减少。结论]甘肃鼢鼠内毛细胞主要感知低频信号。长期的地下生活环境,使其耳蜗发生适应性进化。

| Abstract: | Objective] The research aimed to reveal the auditory characteristics of Myospalax cansu.Method] Using electrophisiologic method,the microstructure of the cochlea in Myospalax cansu was analyzed.Result] The results of scanning electron microscopy showed that the length of outer hair cells stereocilia close to cochlea axis was the shortest and that close to the lateral wall of cochlea was the longest.And the length of stereocilia was gradually longer and longer and the number of stereocilia gradually decre... |
