Talk:Organ of Corti

message: I'm one of the environmental judges at the Brussels Capital District.  We have many cases on the impact of gsm's/mobile phones/wimax technologies and Natura 2000 sites.  Anybody has any knowledge about nuisance between e.g. gsm etc. frequencies and pillars put in Natura 2000 sites - roads passing such sites - and e.g. interference with e.g. frequencies used by bats, in that bats would e.g. stay away from gsm pillars as these bats or other animals can't "see" there anymore?
I assume not as soundwaves are pressure waves and gsm waves are electromagnetic waves and I assume an EM wave doesn't cause a pressure wave, i.e. an audible wave.  But can an EM wave make a little hearing hair vibrate and thus make it audible? Moreover, bats hear in the kHz range and mobile phones are in the MHz range.
"Bats ... hearing range varies by species; at the lowest it can be 1 kHz for some species and for other species the highest reaches up to 200 kHz. Bats that can detect 200 kHz cannot hear very well below 10 kHz.[8] In any case, the most sensitive range of bat hearing is narrower: about 15 kHz to 90 kHz."
From http://en.wikipedia.org/wiki/Insect#Sound_production_and_hearing :"Mosquitoes have been found to hear up to 2 MHz., and some grasshoppers can hear up to 50 MHz."
Quote from GSM frequency bands: the ranges goes from 380.2 to 2.100 MHz.
Can﻿ electromagnetic waves from e.g. gsm masts cause firing of these hair cells? Imagine the foton would be in the frequency or have the wavelength of hair cells? Could it disturb humans or e.g. insects/bat hearing and chase them away from gsm masts?

thread_title:  Sizes 

message: Due to a dearth of basic information about the Organ of Corti itself the following changes have been made:
1. Addition of an introduction, structure, function (with the subcategories of auditory transduction and cochlear amplification), and development of the organ and its associated genes. The previous author's information on clinical significance and hearing loss are maintained.
2. Increase in verifiability of article as a whole and specific pieces of information
3. Reconstruction of page to more logically display information, including revising and weaving in the article's previous information
Due to a question posed regarding sizes of these structures, the following information has also been added:
1. If uncoiled, the cochlea (which is the spiral structure that the Organ of Corti lies in) would roll out to be about 33mm in women and 34mm in men 
For those of us who are looking for precise technical explanations of how the human auditory system works, it would help to answer this question: How many organs of Corti are there relative to the number of stereocilia hairs? It is said that there are about 15,000 stereocilia hairs. Are there that number of organs of Corti as well? The stereocilia hairs "grow" out of hair cells, right? And each hair cell has its own organ of Corti. So there must be fewer organs of Corti than there are stereocilia hairs. That brings me back to my original question: How many organs of Corti are there? …. Thanks, James.  — Preceding unsigned comment added by 2600:8801:B011:300:1436:D705:4D59:218E (talk) 22:48, 5 February 2021 (UTC)
replies: text: Thank you for your addition, but with regard to question about number of hair cells and number of Organ of Corti: NO! Each hair cell does NOT have its own Organ of Corti. Organs are made of tissue, tissue of cells. From 2023 Wiki, the Organ of Corti is a STRIP of epithelial cells, upon which inner and outer hair cells are located, 1 long row of inner hair cells, 3 long rows of outer hair cells, each 'marching' up along that strip, which is that organ.
