A surface called the basilar membrane runs the length of the cochlea.

称为基底膜的表面贯穿耳蜗的长度。

Today your ears heard me tell you how your cochlea, basilar membrane, and hair cells register and transduct sound into action potentials.

今天你的耳朵听到我告诉你你的耳蜗、基底膜和毛细胞是如何记录声音并将声音转化为动作电位的。

Anyway, this sits on top of the basilar membrane and contains up to 20,000 tiny hair cells.

总之，它位于基底膜的顶部，包含多达 20,000 个微小的毛细胞。

The waves of fluid move the basilar membrane, a tissue lined with tens of thousands of hair cells.

流体波移动基底膜，基底膜是一种内衬有数万个毛细胞的组织。

At one end, the basilar membrane is stiff, vibrating only in response to short wavelength, high-frequency sounds.

一方面， 基底膜是僵硬的，仅在响应短波长、高频声音时才振动。

The most important one — at least for our purposes — is the basilar membrane, a stiff band of tissue that runs alongside that middle, fluid-filled chamber.

最重要的——至少对我们来说——是基底膜，一条沿着中间充满液体的腔室延伸的坚硬组织带。

So when your cute little ossicle bones start sending pressure waves up the inner fluid, they cause certain sections of basilar membrane to vibrate back and forth.

所以当你可爱的小小骨开始向内部液体发送压力波时，它们会导致基底膜的某些部分来回振动。

It’s lined with hair cells that have specialized components called stereocilia, which move with the vibrations of the cochlear fluid and the basilar membrane.

它排列着毛细胞，毛细胞具有称为静纤毛的特殊成分，随着耳蜗液和基底膜的振动而移动。

When a sound makes the basilar membrane vibrate, not every hair cell moves - only selected ones, depending on the frequency of the sound.

当声音使基底膜振动时，并不是每个毛细胞都会移动——只有选定的毛细胞会移动，具体取决于声音的频率。

So, the noises made by the seagull and mosquito vibrate different locations on the basilar membrane, like playing different keys on a piano.

因此，海鸥和蚊子发出的声音会在基底膜的不同位置振动，就像在钢琴上弹奏不同的琴键一样。
