In mammalian outer hair cells, the varying receptor potential is converted to active vibrations of the cell body. This mechanical response to electrical signals is termed somatic electromotility; [13] it drives variations in the cell's length, synchronized to the incoming sound signal, and provides mechanical amplification by feedback to the traveling wave.
In the mammalian cochlea, each outer hair cell stands on the soma of a cell of Deiters. What is not apparent in this diagram is that the phalangeal process is tilted out of the plane of this projection, such that its top is near the top of a different outer hair cell, further along in the directional of cochlear wave propagation.
The organ of Corti is located in the scala media of the cochlea of the inner ear between the vestibular duct and the tympanic duct and is composed of mechanosensory cells, known as hair cells. [2] Strategically positioned on the basilar membrane of the organ of Corti are three rows of outer hair cells (OHCs) and one row of inner hair cells ...

The hair cells are arranged in four rows in the organ of Corti along the entire length of the cochlear coil. Three rows consist of outer hair cells (OHCs) and one row consists of inner hair cells (IHCs). The inner hair cells provide the main neural output of the cochlea.
The Human Cell Atlas project, which started in 2016, had as one of its goals to "catalog all cell types (for example, immune cells or brain cells) and sub-types in the human body". [13] By 2018, the Human Cell Atlas description based the project on the assumption that "our characterization of the hundreds of types and subtypes of cells in the ...
The structural change after sound exposure in the Hensen's cells were observed by laser scanning confocal microscopy (LSCM), it showed that after sound exposure, the Hensen's cells moved towed the tunnel of Corti, most of the movement were found in the third row of outer hair cells around with outer part rotates, furthermore, the movement often ...
The reticular membrane (RM, also called reticular lamina or apical cuticular plate) [1] is a thin, stiff lamina that extends from the outer hair cells to the Hensen's cells. [2] The RM is composed of "minute-fiddle-shaped cuticular structures" called the phalangeal extensions of the outer hair cells, interspaced with extensions coming from the ...
