Quick Summary

The Deiters cell, also known as a supporting cell, is a component of the Organ of Corti within the human ear's cochlea. These cells play a crucial role in supporting the sensory hair cells, which are responsible for converting sound vibrations into nerve impulses. Specifically, each outer hair cell is supported by a Deiters' cell, which holds the base of the hair cell in a cup-shaped depression. Projections from the Deiters' cell extend upward to the reticular lamina, a stiff membrane covering the organ of Corti. This structural support is vital for the proper functioning of hearing.1
