Talk:Amniotic sac

message: The amnion is present in all reptiles (which cladistically includes mammals and birds/dinosaurs).  The article as currently written implies that only mammals (and perhaps only humans) have them.
In fact, the technical name for all reptiles and descendants is "amniotes".  Our cousins the amphibians lack the amnion, as do all other animals.
:I think you're probably right, but I'm way too far from my biology texts to prove it right now.   — Jeff G. (talk|contribs) 14:23, 25 February 2007 (UTC)
thread_title:  Too specific to humans 

message: I recall that no one yet understands what organ or process creates (secretes, excretes) amniotic fluid.  Sure, the fetus ingests the fluid and cycles it out the urinary tract, but from where does it originate?  How do all those components get there?  From the mother?  Or does junior manufacture it?  I always thought it was blood plasma-like substance filtered by the kidneys and out the urethra, but I ain't no MD. --Robertkeller 00:10, 15 July 2006 (UTC)

message: "Some sources consider it to be equivalent to the amnion". Well, are they or are they not referring to the same term? If yes, the articles should be merged. If no, the distinction should be clarified. /skagedal... 08:41, 24 November 2008 (UTC)

thread_title:  [[Amnion]] – Clarify distinction, or merge 

message: The drawing from Gray's Anatomy is nice, but not correct: The chorion in reality is not sticking to the amnion but to the uterus. Tomdo08 (talk) 03:08, 2 August 2009 (UTC)
replies: text: You are right; "wrong" is definitely the wrong word here :) What I should have said, is "potentially misleading". The reason for my remark was, that on my search for material I found a lot of wrong descriptions, which put amnion and chorion together or even omitted one of them. I felt, that the drawing is not clear enough to avert such interpretations. But in the end, it's certainly good enough. -- Tomdo08 (talk) 20:35, 8 August 2010 (UTC)

message: Hi Wolfch! I noticed that you upgraded the article from start-class to C-class for WikiProject Animal anatomy. The article does not actually give much detail on animals, which is why its class rating is lower than for the other 2 relevant WikiProjects. Would you consider moving the class rating back down to start-class? Thanks! Bibeyjj (talk) 15:46, 29 December 2020 (UTC)
replies: text: Ok. I tried to use the same class rating for different WikiProjects. I ignored that the same article may have different ratings for different WikiProjects. I restore the edit. Thank for sugguestion--Wolfch (talk) 15:51, 29 December 2020 (UTC)
