内、外毛细胞不仅本身在数量上和形态结构上有所不同,而且支配它们的传入和传出神经结构亦有差别。由此所提出的内耳两种感觉神经系统—内毛细胞感觉神经系统和外毛细胞感觉神经系统—在生理性和病理性(噪声、内淋巴积水等)刺激下,各自具有不同的反应。本文拟就这两种感觉神经系统分别从形态结构和功能上以及病理上加以阐述。 Both inner and outer hair cells differ not only in their quantity and morphology, but also in their afferent and efferent neural structures. Thus, two sensory nervous systems of the inner ear, the inner hair cell sensory nervous system and the outer hair cell sensory nervous system, have been proposed to respond differently by physiological and pathological stimuli (noise, endolymphatic hydrops, etc.). In this paper, we will elaborate on these two kinds of sensory nervous system from morphological structure and function as well as pathology.
