Hensen's cell

Hensen's cell is a type of supporting cell found in the organ of Corti in the cochlea of the inner ear. Named after the German anatomist Victor Hensen, these cells play a crucial role in the auditory system.

Structure

Hensen's cells are located in the outermost region of the organ of Corti, adjacent to the outer hair cells. They are elongated cells, extending from the basilar membrane to the tectorial membrane. They are characterized by their large, oval nuclei and a high number of mitochondria, indicating their high metabolic activity.

Function

The primary function of Hensen's cells is to provide structural support to the organ of Corti. They also play a role in the regulation of the ionic environment in the cochlea, which is essential for the proper functioning of the hair cells. Some studies suggest that Hensen's cells may also be involved in the active amplification of sound signals, although this is still a topic of ongoing research.

Clinical significance

Damage to Hensen's cells, like other cells in the cochlea, can lead to sensorineural hearing loss. This can be caused by various factors, including exposure to loud noise, aging, and certain medications. Research is ongoing to develop treatments that can protect or regenerate these cells to restore hearing.
