cochlear duct

蝸管

1.蝸管(cochlear duct)位于耳蝸內(nèi)的膜性管道,形似耳蝸,但管腔小,其頂端為盲端,底部借連合管與前庭內(nèi)的膜性囊相通(參見圖11-11),內(nèi)充以內(nèi)淋巴. 在蝸軸的垂直切面上,可見蝸管呈三角形,共有三個壁. (圖11-13):2.螺旋器(spiral organ)又稱柯蒂(Corti)氏器為聽覺感受器.

otoscopy

耳鏡檢查

2.耳鏡檢查(otoscopy) 當耳道狹小或炎癥腫脹時,用漏斗狀的耳鏡(耳道撐開器)撐開狹窄彎曲的耳道,避開耳道軟骨部耳毛,保證光源照入. 耳鏡管軸方向與外耳道長軸一致,以便窺見鼓膜. 骨性耳道缺乏皮下脂肪,無伸縮性,故耳鏡前端勿超過軟骨部,
