Untitled[edit]

Recently vandalized. I repaired it. Keep an eye on it.

Mneumonic[edit]

I'm torn; as a medical student the "C3, 4, and 5 keep the diaphragm alive..." (referring of course to the phrenic nerve) was useful, but I don't feel like it's within the scope of Wikipedia What Wikipedia is not. Where could I move it? Eps0n (talk) 03:15, 24 June 2009 (UTC)

Thoracic outlet / Inferior thoracic aperture[edit]

The article stated that the peripheral muscle fibers extend from the Thoracic outlet. When I click on Thoracic outlet, it takes me to the superior thoracic aperture, which is the opening at the top of the rib cage at the first rib. I believe that the diaphragm actually arises from the inferior thoracic aperture (i.e. the bottom of the ribs/xiphoid process/ T12 vertebrae). I think someone put Thoracic outlet down correctly, but there is confusion between what the outlet/inlet is as some texts refer to the Sup. aperture as the 'inlet', others call it the 'outlet'....

Summary: I changed Thoracic outlet to Inferior Thoracic aperture. I'm not an expert, so someone may want to clarify etc. M0rt (talk) 04:00, 19 April 2009 (UTC)

Valsalva maneuvre[edit]

New to editing and don't want to edit the article, but somebody could add info on the valsalva maneuvre to the functions-part..

Proposed name change[edit]

I suggest changing the name to Diaphragm (thoracic). Diaphragm (anatomy) could refer to any of several structures. - ATDDFTdrdtftd rsdadawadawadawadaawwsasudspaulyapoag fyafgydfyfyaff ffugygfs]\nononononononononononononononononononoyesysyeysyesysyeysyeys sgls WFSYFSSGFHFHAGFHGFHAFGAYano heuwifhuihyfjgfrtwdeftqfeadrdsaESWRGHTUHTHIS RYUTREYFWUSAIUDFFEUUIAUAUAYYDUYSUYFUSYFUYFUSYFSFSFGHGFSGFSgFSGFGSFGSFGFGrdcavell 06:09, 19 September 2006 (UTC)

I think it should be "Thoracic diaphragm" by comparison to urogenital diaphragm and pelvic diaphragm (and because the word in parenthesis should be the subject area, not the anatomical region). But I agree that "Diaphragm (anatomy)" is an oddly ambiguous choice.  — JVinocur (talk • contribs) 11:10, 19 September 2006 (UTC)
Actually, I see that Thoracic diaphragm already exists as a redirect to Diaphragm (anatomy). So we could easily just swap those two pages so the redirect points the other direction.  — JVinocur (talk • contribs) 11:12, 19 September 2006 (UTC)
Yes, thoracic diaphragm is better. At least it would move this structure outside the namespace of diaphragm (the disambig page). - Richardcavell 22:43, 19 September 2006 (UTC)

Um.... in the first paragraph it says the Penis is the shelf of muscle.... Isn't that supposed to be diphragm? Looks like the vandal struck again. I say we sack him! Anonymous Joe

Diaphragm Dictionary Definition[edit]

While the dictionary definition might be interesting, I don't think that it is altogether necessary and, to me, it clutters the site up a little. Maybe the caption could be shortened or something similar, but it's sort of distracting. 66.52.218.100 07:37, 14 December 2006 (UTC)

Removed something[edit]

I've removed this sentence from the intro:

It is also connected to the the muscle and connective tissue.

It was written by an anonymous editor, so I can not ask him/her. It has a grammatical mistake. I don't know if it's true (I don't know much about anatomy), but there is no reference to easily verify it. And even if it is true, it does not sound so important as to be put in the intro. It does not seem to be related to the previous sentence.

If you are more educated than I am, please feel free to put it back, if it has a place in the article.--CyHawk (talk) 14:11, 6 November 2008 (UTC)


Mandy is taking a EMT class and it was confusing... so I think the diaphragm stinks. =( —Preceding unsigned comment added by 99.146.117.59 (talk) 07:20, 6 February 2009 (UTC)

Avian diaphragms - yes, or no?[edit]

Not an expert in anatomy, and not looking for this particular factoid. Just noted that in the beginning half of a paragraph it is written that a bird's lungs are above its diaphragm, then in the following half of the same paragraph it is written that birds do not have diaphragms; which is it?Patent.drafter (talk) 16:52, 22 August 2011 (UTC)


Birds, and amphibians and almost all (perhaps all) reptiles do not have true diaphragms. Mammals do, and some of the mammal-like reptiles may. The evolution of the diaphragm is still a little hazy. I'm studying zoology. (I removed a bit from the intro that implied that amphibians and reptiles had true diaphragms) — Preceding unsigned comment added by 82.43.146.211 (talk) 15:32, 28 December 2012 (UTC)

Proposed merge with Caval opening[edit]

Needless fragmentation; would enhance the quality of information to have on a single article; would also be of greater benefit to readers LT910001 (talk) 12:21, 28 February 2014 (UTC)
