Talk:Pylorus

It has no theology, or geometry ==

I vote this be moved to pyloric sphincter -> nobody calls it a valve. (I read some where not to be hasty in moves)

Valves are what you have in your heart. your mouth, ass and pylorus are sphincters.--ZZ 03:16, 18 Sep 2004 (UTC)

How about just "pylorus" -- anatomically correct? Barry Zuckerkorn 19:20, 24 January 2006 (UTC)

Ignatius J. Reilly refers to it quite often as a valve. He is, I'm sure, far more superior in intelligence to the likes of you.

-- stay put, I'm among the undoubted many who come to this subject through Ignatius. Valve is helpful.

Sphincter/Valve
sphincter means 'ring of muscle'

see en.wikipedia.org/wiki/Sphincter

I might update Wiktionary after this. Here's hoping it's the best definition on google (define: sphincter).

Valve/Sphincter
or I could edit wiktionary or wikimedical or whatever-the-hell-it's-called. It's taken me 30 minutes to figure out how to edit this one article and I haven't done it yet.

Might not bother.

Significance of Sphincter
Shouldn't there be something on the purpose or significance of the sphincter, or I guess the function? Considering that the cardiac sphincter, the proverbial sister of the pyloric sphincter, has a purpose/function to ensure that there isn't backflow into the esophagus that would burn the esophagus.

It could be something along the lines of: "As a sphincter, the pylorus, as it is also known as, ensures that there is regulation in the movement of food between the stomach and small intestine. Thus there is a flow in the movement and it ensures that the stomach first completes its purpose in digestion and then the acid chyme can enter the small intestine. This regulation also protects the small intestine since a constant influx of acid into the duodenum would be harmful towards the vital enzymes in the small intestine, such as the pancreatic amylase, which denature at low pH levels."

That isn't a quote, I just wanted to make sure it was obvious what I meant.

The contraction of the pylorus stimulates the release of a peptide in the stomach that registers being full in the brain through a nerve i can't remember...


 * I agree -- this article should say a few words about its purpose and function.
 * In particular, I came to this article to find out:
 * How does the stomach "know" when to hold on to food and digest it a little longer, and when to release it into the intestines?
 * Not only does this article not answer my question, it doesn't even mention this hold/release activity. --DavidCary (talk) 01:37, 23 July 2013 (UTC)

Merger suggestion Pyloric antrum => Pylorus
from edit summary: the content of Pyloric antrum and Pylorus are much overlapping but not redundant; Pyloric antrum speaks to an anatomical substructure. --User:Ceyockey ( talk to me ) 01:14, 30 June 2007 (UTC)

Proposed merge
Hello to all! I am proposing a merge from the following articles into this article:
 * Pyloric canal
 * Pyloric antrum

This is for the following reasons:
 * I plan to significantly expand the article on pylorus in the future and feel that it would be better to have the canal and antrum covered in this section under a 'structure' subheading. This would allow comparison between blood supplies, venous drainage, lymphatic and nervous supply.
 * The main article would benefit significantly from having all this information in one place.
 * It would improve the anatomical content to have this all in one place.
 * The increased readership would hopefully impact on article quality in the future.

Kind Regards, LT910001 (talk) 01:05, 9 November 2013 (UTC)
 * ✅ with no objections, this merged has been performed. --LT910001 (talk) 23:35, 8 June 2014 (UTC)

Proposed merge with Pyloric glands
Needless fragmentation; would be better presented under pylorus/histology. Would enhance information to have it displayed in context. LT910001 (talk) 01:47, 28 December 2013 (UTC)
 * ✅ with no objections, this merge has been performed. --LT910001 (talk) 23:35, 8 June 2014 (UTC)

Confusion About Pyloric Antrum
Student of anatomy, first time commenting: I'm looking for info on the pyloric antrum, and the description here seems to be at odds with the illustrations, or at the least unclear. Please edit for greater clarity:

From the article: "Pyloric antrum (lesser cul-de-sac) is the initial portion of the pyloric part of the stomach."

The illustrations show two portions at the lower end of the stomach, with the second one labeled antrum. The description seems to say the opposite, that the antrum is the first part. I can't clarify this but other sites show mixed information. see: medical-dictionary.thefreedictionary.com/antrum

 * Thanks for your comments,, and welcome to Wikipedia! Please feel free at any time during your studies to point our errors or inconsistencies like this, or, even better, find a reliable source like a textbook and make the change yourself! I'm one of the editors at WP:ANATOMY and we're already looking to collaborate with other editors to improve the encyclopedia. Cheers, --LT910001 (talk) 23:35, 8 June 2014 (UTC)

Use of gastric antrum
Have introduced gastric antrum into Antrum section - it is far more usual than pyloric - nGrams and Google hits.--Iztwoz (talk) 21:15, 27 March 2024 (UTC)
