Question

Dieter’s cells are found in
A. Reissner’s membrane
B. Malleus
C. Organ of Corti
D. None of the above

Answer 1

Hint:- Also known as “cells of Dieters” or “phalangeal cells”, the dieter’s cells are cells that contain microtubules and microfilaments running from the basilar membrane region to the reticular membrane region of the ear. They support the outer hair cells by providing a cup-like structure.

Complete Answer:-
Deiters cells are functionally present to support the cochlea of the inner ear. The fluid-filled cochlea with snail-like anatomy constitutes a spiral organ called the organ of Corti. The organ of Corti acts as the receptor for the hearing which receives signals from the oval window of the ear which in turns receives it from the malleus through the stapes.
Thus, in the given question, the options are structures present in the ear that are closely associated with each other and Dieter’s cells. However the malleus is the part of the middle ear and helps in receiving the signals that are passed on to the organ of Corti which is part of the inner ear and the Reissner’s membrane is a diffusion barrier in the inner ear, eliminating the options A, B and naturally D. So, among the given options, the correct answer is option C, Organ of Corti.

**So, among the given options, the correct answer is option C, Organ of Corti.

Note:- The cells of the organ of Corti have small hairs that help in the transmission of the sound pressure waves through the fluid in the cochlea. The outer hair cells are supported by the phalangeal Deiter cells which provide a cup-like structure to hold the base of the hair cells.
