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.
Deiters' cells, also known as outer phalangeal cells or cells of Deiters (English: / ˈ d aɪ t ər z /), are a cell type found within the inner ear. They contain both microfilaments and microtubules which run from the basilar membrane to the reticular membrane of the inner ear.

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 ...
Type I spiral ganglion cells comprise the vast majority of spiral ganglion cells (90–95% in cats and 88% in humans [2]), and exclusively innervate the inner hair cells. They are myelinated, bipolar neurons. Type II spiral ganglion cells make up the remainder. In contrast to Type I cells, they are unipolar and unmyelinated in most mammals.
The inner root sheath (IRS) consists of: a delicate cuticle next the hair, composed of a single layer of imbricated scales with atrophied nuclei; Huxley's layer; Henle's layer; The term "trichilemmal" refers to the outer root sheath. [2] The IRS functions to mould, adhere, as well as participate in the keratinization of growing hair. [3]
The inner root sheath or internal root sheath of the hair follicle is located between the outer root sheath and the hair shaft. [1] It is made of three layers: Henle's layer, Huxley's layer, and the cuticle. [2] The inner root sheaf serves to protect growing hair. [3]
