标题： The avian tectorial membrane: Why is it tapered?

摘要： 虽然哺乳动物和鸟类的内耳都有明确的听觉频率组织，以及专门用于运动和感知作用的毛细胞，但鸟类耳朵的结构组织与其哺乳动物的耳蜗 counterpart 不同。 这种差异可能源于运动毛细胞功能方式的不同。 短毛细胞的作用被认为类似于哺乳动物的外毛细胞，可能依赖于它们的毛束，而不是细胞体的运动，来提供耳蜗放大器的运动元件。 本报告重点探讨鸟类盖膜的作用，具体是回答这个问题：“为什么鸟类的盖膜从神经方向到非神经方向呈锥形？” 显示英文摘要

摘要： While the mammalian- and the avian inner ears have well defined tonotopic organizations as well as hair cells specialized for motile and sensing roles, the structural organization of the avian ear is different from its mammalian cochlear counterpart. Presumably this difference stems from the difference in the way motile hair cells function. Short hair cells, whose role is considered analogous to mammalian outer hair cells, presumably depends on their hair bundles, and not motility of their cell body, in providing the motile elements of the cochlear amplifier. This report focuses on the role of the avian tectorial membrane, specifically by addressing the question, "Why is the avian tectorial membrane tapered from the neural to the abneural direction?"
