Summary Introduction

To describe:

The structure and function of various parts of the human ear by tracing the route of a sound wave from the air outside the ear to action potentials in the auditory nerve.

Introduction:

The ear is the most sensitive organ among all of the “sense organs”. It provides the hearing ability to every individual. It has three parts: the outer ear, inner ear, and middle ear. Apart from hearing, it also helps in balancing the body and also maintains body posture. It transmits sound waves in the form of nerve impulses to the brain that result in the sensation of hearing and equilibrium.
