Information about Deiters' cells and related anatomical structures

Anatomy

Deiters' cells, also known as phalangeal cells, are specialized supporting cells found in the Organ of Corti within the cochlea of the inner ear. These cells play a crucial role in the auditory system by providing structural support to the outer hair cells and contributing to the overall function of hearing.

Structure

Deiters' cells are located in the Organ of Corti, which is the sensory organ responsible for detecting sound vibrations and converting them into neural signals. Each Deiters' cell has a slender, columnar shape and extends from the basilar membrane to the reticular lamina. The upper part of the cell, known as the phalangeal process, supports the base of an outer hair cell, while the lower part anchors to the basilar membrane.

Function

The primary function of Deiters' cells is to provide mechanical support to the outer hair cells, which are essential for the amplification and fine-tuning of sound waves. By stabilizing the outer hair cells, Deiters' cells help maintain the integrity of the Organ of Corti and ensure the proper transmission of auditory signals to the auditory nerve.

Clinical Significance

Damage or dysfunction of Deiters' cells can lead to hearing impairments, as the loss of structural support for the outer hair cells can disrupt the normal functioning of the Organ of Corti. Research into the role of Deiters' cells in hearing loss and potential regenerative therapies is ongoing.
