Chapter 10: Problem 2

The purpose of the eardrum is to protect the sensitive nerves underneath it. It serves no purpose in actual hearing. True or false?

Short Answer

Expert verified
False

Step by step solution

01

Understanding the Eardrum

The eardrum, also known as the tympanic membrane, is a thin, cone-shaped membrane that separates the external ear from the middle ear. It is crucial to understand its role in the sense of hearing.
02

Function of the Eardrum

When sound waves enter the ear, they strike the eardrum. The energy of the sound wave is transferred to the eardrum, causing it to vibrate. These vibrations then move the tiny bones in the middle ear, which send the sound wave information further into the interior ear for further processing. In summary, the eardrum plays a vital role in converting external sounds into mechanical energy that can be processed further within the ear.
03

Evaluating the Given Statement

The statement suggested that the eardrum only serves to protect sensitive nerves and does not contribute to hearing. However, as we have seen in the previous step, the eardrum indeed plays an essential role in the hearing process, making the original statement False.
