Talk:Lanugo

message: I have rephrased this section to be shorter and more to the point and logical. If lack of food really does cause terminial or vallus hair to revert to lanugo (which from my own knowledge of human anatomy and physiology I am highly inclined to doubt, but no matter if it is sourced) then it shouldn’t make any difference wheather the stravation of a patient was intentional on their part or not.

message: In what way consume? as in eat orally or just absorb back into the body or fall out in the womb to be injested orally?
:It's ingested orally while the fetus is still in the womb. I'm not sure of the mechanics of how it reaches the fetus' mouth. JF Mephisto 21:24, 20 July 2006 (UTC)

message: The claim about Languo growth in anorexics needs a citation.  I've put in an albeit weak one, but it proves hair growth to be a response to anorexia. |spetz|68.44.192.170 21:06, 26 November 2006 (UTC)
thread_title:  Citation 

message: Hair does normally grow on the abdomen, chest, and back, both in adults and babies.  Fine vellus hair is normally present in all these locations in both sexes, and in adult males and some females varying amounts of terminal hair are also present.  Therefore I am changing this sentence.

thread_title:  What does this sentence mean? Is it true?  

message: Why is there an image of normal human hair on this page? It's not lanugo. Is this necessary? It could also be considered misleading. The only context in which normal human hair should be pictured in this article is with a comparison between normal hair and lanugo. Would an encyclopedia do this just because they didn't have an image of the article's subject?Mjpresson (talk) 15:45, 20 August 2008 (UTC)

message: In the section Fetal Development, it is said that the Lanugo is shed and replaced by vellus hair at about 40 weeks of gestational stage. That would mean by the time of birth? Is it right?  —Preceding unsigned comment added by Malassn (talk • contribs) 15:58, 28 March 2009 (UTC)
replies: text: The article gives three different times of disappearance in three different spots. Before birth, just after birth, within a few months after birth. What gives? 129.132.209.199 (talk) 12:04, 20 May 2014 (UTC)
thread_title:  Duration of Lanugo 

message: The article currently reads: "Lanugo can be explained only as a remnant of our primate ancestry: fetal monkeys also develop a coat of hair at about the same stage of development. Their hair, however, does not fall out, but hangs on to become the adult coat. There is no need for a human embryo to have a transitory coat of hair, the womb is a cozy 98.6 degrees Fahrenheit, and yet we have a furry human fetus.[1]
A hypothesis, according to the NHS, is that lanugo has to do with temperature regulation.[2]"
So which is it? Is it purely vestigial, or is there some useful function? Perhaps it is not yet known. In any case, the wording is inconsistent as it stands.  — Preceding unsigned comment added by Whatthefat (talk • contribs) 17:38, 21 December 2011 (UTC)

message: And exactly what is NHS?  We lesser evolved 'merikans do know about no commie "National Health Services" thing from the old country.  Seriously though, you need to state what that is, and explain that some spokes person said that, or its in their literature, or wherever the hell you got that from and probably turn it into a citation.

thread_title:  According to the NHS ... 

message: I think this deserves some comment on it being a vestigial feature from our primate ancestry.  — Preceding unsigned comment added by 90.202.28.172 (talk) 12:26, 9 March 2013 (UTC)

thread_title:  External links modified 

message: This term is often (apparently mistakenly, but in mainstream albeit non-medical secondary sources) applied to downy hair growth as result of hormonal imbalances caused by eating disorders in teens and adults. We should disambiguate (with a hatnote, with a note in the text that the term is sometimes misapplied, or with "See also" entry.  I used to know what the proper term was but have spaced it.  — SMcCandlish ☏ ¢ 😼  23:07, 22 February 2019 (UTC)
thread_title:  Eating disorders 

message: The current article includes some paper-cited hypothesis that lanugo may serve to hold the vernix caseosa and might play a role in lubrication.  Isn't it often already gone before birth, with some of the remnants possibly randomly stuck on it (with most usually eaten/digested)?  Doesn't the vernis cover the whole body rather than only the lanugo area?  Since it's sometimes completely lost before birth but persists shortly after in other cases, if it served an important lubrication role, wouldn't it also correlate with birth difficulties?  Another popular hypothesis is that it's vestigial (since it persists in other great apes), but there's no current mention of this.  Thanks, —PaleoNeonate – 07:09, 6 June 2020 (UTC)
