Abstract
The inner ear consists of the cochlea, which contains the sensory organ responsible for hearing, and the vestibule, which contains the snesory organs for balance and equilibrium. This chapter describes the morphological structure of the cochlea, including the organ of Corti, the end organ for hearing, which contains sensory cells (i.e., inner and outer hair cells), supporting cells, and spira ganglion cells (i.e., primary auditory neurons); the basilar membraine, which is set in motion by movement of the tympanic membrane and ossicular chain; and fluid spaces (i.e., scale vestibuli, media, and tympani). The inner and outer hair cells are responsible for transducing the mechanical waves of the basilar membrane into electrical impluses that are transmitted by the spiral ganglion cells to the brain for the perception of sound.
