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. While the eardrum does protect the nerves of the ear, it also plays a vital role in the process of hearing.

Step by step solution

01

Understanding the function of the eardrum

The eardrum, or tympanic membrane, is a thin layer of tissue that separates the outer ear from the middle ear. It vibrates when sound waves hit it, and these vibrations are then transmitted to the bones of the middle ear.
02

Evaluating the statement

The statement claims two things: 1. That the eardrum's purpose is to protect the nerves underneath it. 2. That the eardrum plays no part in hearing. The first part is correct, the eardrum does offer a level of protection to the middle and inner ear. However, the second part of the statement is incorrect. As we identified in Step 1, the eardrum plays a significant role in the hearing process.
03

Formulating the answer

Given that one part of the statement is true and the other is false, the whole statement must be considered false. Even though the eardrum does offer protection to the nerves in the ear, it is incorrect to say it serves no purpose in hearing.
