Question: 1 / 400

What body part vibrates in response to sound waves, transmitting them further into the ear?

Ear drum

The ear drum, also known as the tympanic membrane, plays a critical role in the process of hearing. When sound waves enter the ear canal, they cause the ear drum to vibrate. These vibrations are the first step in the conversion of sound waves into signals that the brain can interpret. Once the ear drum vibrates, these vibrations are transmitted to the bones of the middle ear, which further amplify and convey the sound waves into the inner ear.

This makes the ear drum essential for hearing as it is the first point where sound waves physically interact with a body part to generate vibrations. The correct functioning of the ear drum is crucial for capturing sound properly, marking it as the primary vibrating structure within the ear in response to external sound waves.
