声音是怎样进入内耳听觉器官的呢?起初,被耳壳捕获的声音进入外耳道,然后被鼓膜接收。鼓膜的微弱而幅度大的振动必须转化为较强而幅度较小的振动,以便能引起内耳液体的振动。这个任务落在一个由三块小骨组成的系统上。这三块小骨就是锤骨、砧骨和镫骨。鼓膜的振动首先传到锤骨上, How does the sound enter the auditory organ of the inner ear? Initially, the sound captured by the concha enters the external auditory canal and is then received by the tympanic membrane. The weak and large vibration of the tympanic membrane must be converted into a stronger, less intense vibration so as to cause vibrations of the liquid in the inner ear. This task falls on a system of three small bones. These three small bones are the malleus, the incus and the stapes. The tympanic membrane vibration first spread to the malleolus,
