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

镫骨肌神经，为中耳镫骨肌提供运动纤维。

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，它支配镫骨肌；镫骨可以传递从耳膜来的震动；而镫骨肌可以减轻镫骨的震动，从而保护我们的耳朵免受巨大噪音的干扰。
