Summary Introduction

To describe: The structures of the inner ear involved in equilibrium.

Concept introduction: The ear is the hearing organ that detects sound and the movements of the brain. The stimulus is transduced into nerve signals. Nerve signals are then transmitted by the vestibular nerve (eighth cranial nerve) and results in the sensation of hearing and equilibrium. Anatomically, the ear is divided into three distinct regions, namely external ear, middle ear, and inner ear.
