In what part of the auditory analyzer does sound vibrations turn into impulses?

The analyzer is a special system that regulates the senses. It consists of three parts: a receptor, a sensory nerve and a corresponding zone in the cerebral cortex.

In the first part of the analyzer – the receptor, the perception of irritation (in this matter, the sound vibration) takes place and its transformation into a nerve impulse. For a specific sense organ, there is a specific part where the receptor is located. For the auditory analyzer, this part is the so-called “cochlea” – a part of the inner ear.
