What is a 'neutron of force'?

edit

Why did you revert? Neutrons are not involved in the process of hearing. Perhaps this is a misspelling of 'newtons'? --Ehinson56 15:46, 6 November 2006 (UTC)Reply

First time here, hope I'm doing this correctly. Question: Why does loud, intense noise result in high frequency deafness?xxxx

Actin Filament Terminology

edit

from the wikipedia page regarding actin: The polarity of an actin filament can be determined by decorating the microfilament with myosin "S1" fragments, creating barbed (+) and pointed (-) ends on the filament. An S1 fragment is composed of the head and neck domains of myosin II.

the original use of the barbed/pointed terminology was misleading in that it implied that this was an actual characteristic of actin rather than simply due to a procedure performed in order to determine +/- orientation within cells. If mention of barbed and pointed is going to be made it should be linked to this page with a short explanation. This seems unnecessary however as that detail is not important to the understanding of stereocilia; positive/minus terminology is sufficient. —Preceding unsigned comment added by Repapetilto (talkcontribs) 00:29, 14 December 2007 (UTC)Reply

Number

edit

What is the number of stereocilia in a normal, undamaged human inner ear? Is it 15 to 20 thousand? Can this be added to the article? Badagnani (talk) 21:26, 13 September 2008 (UTC)Reply

Mechanoelectrical Transduction

edit

The mechanoelectrical transduction section of this page was lacking detail, so I added content that explained how the transduction channels in the sterecilia work. Including more information gives a better idea of how stereocilia function. I also changed the sentence about stereocilia being stimulated by the shear force of the endolymph, since that statement was not entirely accurate. Instead, in the cochlea, it is the movement of the tectorial membrane that puts force on the stereocilia.Ktrychta (talk) 03:52, 2 December 2011 (UTC)Reply

I edited and pruned that section a bit, as it had other inaccuracies, as well. As for the TM being the stimulus the stereocilia, that's highly questionable. The IHC stereocilia probably don't touch the TM, so are only moved by fluid motion. Dicklyon (talk) 05:28, 2 December 2011 (UTC)Reply
