Others may be less so, like the buccinator, a muscle that attaches your cheek to your teeth, or the body's tiniest skeletal muscle, a one-millimeter-long tissue fragment called the stapedius that's nestled deep inside the ear.

其他肌肉就比较陌生了，比如颊肌，这是一种把颊连接到牙齿上肌肉，还有身体上最纤细骼肌，一片一毫米长组织材料，叫做镫肌，位耳朵深处。

Nerve to stapedius, which then supplies motor fibres to stapedius muscle of the middle ear.

镫肌神经，为中耳镫肌提供运动纤维。

In the ear, it innervates the stapedius muscle which dampens the vibration of the stapes, a small bone that help transmit vibrations from the eardrum; this protects you from loud noises.

在耳部，它支配镫肌；镫可以传递从耳膜来震动；而镫肌可以减轻镫震动，从而保护耳朵免受巨大噪音干扰。
