inner ear anatomy

Quick Summary

The inner ear contains the organ of Corti, which houses sensory hair cells responsible for hearing. Among these are the inner hair cells, which are crucial for converting sound vibrations into nerve impulses that are sent to the brain. These cells are arranged in a single row and are supported by specialized cells. When sound waves travel through the inner ear, they cause vibrations that bend the stereocilia (hairlike projections) on the inner hair cells. This bending triggers the release of neurotransmitters, which stimulate nerve fibers, ultimately leading to the perception of sound. The inner hair cells are the primary auditory receptors, transmitting the majority of auditory information to the brain.12
