问题 单项选择题

旅客闭眼坐车时,也能准确辨析汽车行驶速度的变化,以及是否在上下坡行驶,接受这种刺激的感受器位于()。

A.鼓室和半规管

B.前庭和半规管

C.前庭和耳蜗

D.鼓室和耳蜗

答案

参考答案:B

解析:

B。解析:鼓室内有空气维持鼓膜两侧的气压平衡;半规管、前庭内有感受头部位置变动的位觉(平衡觉)感受器,前者引起旋转感觉,后者引起位置感觉和变速感觉。前庭及半规管过敏的人,在直线变速及旋转变速运动时,传人冲动引起中枢有关部位过强的反应,导致头晕、恶心、呕吐、出汗等,这就是有些人晕船、晕车的原因;耳蜗内有听觉感受器,感受刺激并产生神经冲动。因此旅客闭眼坐车时,也能准确辨析汽车行驶速度的变化及是否在上下坡行驶.是依赖位于前庭和半规管的感受器来传递刺激,故选B项。
