Deiters cells

Deiters' cells (also known as phalangeal cells) are a type of supporting cell in the cochlea of the inner ear. They are named after the German anatomist Otto Deiters, who first described them.

Etymology[edit | edit source]

The term "Deiters' cells" is derived from the name of the German anatomist Otto Deiters, who first described these cells. The term "phalangeal cells" refers to their shape, which is similar to the phalanges (bones) of the fingers and toes.

Structure[edit | edit source]

Deiters' cells are located in the organ of Corti, the sensory organ of the cochlea. They have a long, thin shape, similar to the phalanges of the fingers and toes, which is why they are also known as phalangeal cells. Each Deiters' cell supports one outer hair cell, which is responsible for detecting sound vibrations.

Function[edit | edit source]

The primary function of Deiters' cells is to support the outer hair cells in the cochlea. They help maintain the structure of the organ of Corti and provide physical support to the hair cells. In addition, they may also play a role in the transmission of sound vibrations to the hair cells.

Clinical significance[edit | edit source]

Damage to Deiters' cells can lead to hearing loss, as they play a crucial role in the function of the cochlea. Certain drugs and loud noises can damage these cells, leading to sensorineural hearing loss. In addition, some genetic conditions can affect the structure and function of Deiters' cells, leading to congenital hearing loss.
