Could someone please explain to me why the mneumonic keeps getting removed Albert109 05:46, 2 May 2006 (UTC)[reply]


The page says "Epidermis is divided into several layers where cells". Should it be "several layers of cells, where [cells]"?

There's an excellent drawing of the skin at Commons, but since I'm not an expert I'm uncertain if it is relevant here. Thuresson 17:39, 31 Mar 2005 (UTC)


Please forgive my rookieness, I couldn't find where to comment on this particular discussion thread, so I'll add it here. I am currently in Biology 201 and we're covering this exact topic. Acoording to my textbook entitled "Human Anatomy" by Michael McKinley and Valerie Dean O'Loughlin on page 122, numbers one and two in the picture here at wikipedia are not separate layers. Epithelium cells are located throughout the dermis and epidermis. I shall do my best to label the picture as it should be according to my text book:

1 & 2 - epidermis layer. The basement membrane of the epidermis is the very bottom line of the epidermis layer (the wavy line).

3 - dermis layer

3 - subcutaneous fat (adipose)

You are correct, 1&2 are both part of the epidermis. The diagram should probably indicate that 1 is the acellular keratin layer (stratum corneum) while 2 is the cellular epidermis (stratum granulosum, stratum spinosum, stratum basale). I would make the appropriate change. 98.196.108.245 22:37, 1 November 2007 (UTC)DocP== Merge of epidermis and skin ==[reply]

I'd say merge the info about humans into epidermis, and skin should have general info on skin of all animals and focus on either general, or non-human info about skin.

Definitely in favour of a total merge. Not sure how you could create the article suggested above - nice idea but I just can't work it out - surely one general article on skin is enough for wikipedia with the separate pages that already exist containing more detailed biological information Madmedea 17:00, 2 January 2007 (UTC)[reply]

~Epidermis is also found in plants. Vote no for the merger myself.

I agree, The epidermis should focus more on humans, while skin expand to cover all plants/animals with skin. Ard0 (Talk - Contribs) 03:27, 23 January 2007 (UTC)[reply]

Regarding the proposed merge, the epidermis is just *part* of the skin. -- Schneelocke 12:56, 17 February 2007 (UTC)[reply]
No to the merger. As stated above the apidermis is one part of the skin, and all parts need an article. We have lots of articles on dermatology. Whether our articles are currently too human-specfic is another issue. I don't see that contracting the skin articles will be of benefit regardless Secretlondon 00:00, 7 March 2007 (UTC)[reply]

Replaced page

[edit]

I replaced the page, which had been converted into a redirect. My big reason for this was that the content was not transferred over, plus I'm not really convinced that everyone has had a chance to weigh in on the possible options besides merging. WLU 18:36, 26 January 2007 (UTC)[reply]

- Definately no merger The epithelium is a discrete tissue layer. It is distinct from other dermal layers, with its own structure and properties. It should remain its own page, I think, but maybe with a general overview under skin, with more technical bits here. It would be like combining oesophagus, stomach, small intestine, colon, rectum and anus together under the title "Gastrointestinal tract". No good. I know there is an entry under GI tract, but imagine no specific page for the colon. DoctorReiux 12:31, 20 March 2007 (UTC)[reply]

If you're voting on the merge, rather than using a sub-heading it's more standard to use a bullet and bold:
  • Merge or Don't merge.
Also, the spelling of words is less important than the wikilinks - esophagus takes you direct to the page, while oesophagus shunts through a re-direct. And on talk pages, it doesn't matter. Anyway, the pages need the eye of someone knowledgeable in the subject, so feel free to make the changes you'd like, ideally put in your references as well. WLU 15:50, 20 March 2007 (UTC)[reply]

Epidermis is definatly not the same as skin and therefore shouldn't be merged. It would make more sence to merge skin and flesh and they have there own articles.

English

[edit]

I think it'd be smart to learn how to speak English reasonably well before you write for the English Language version of Wikipedia. Apparently, someone has been working on this article who isn't very familiar with English. I can tell because parts of it sound like crap. —Preceding unsigned comment added by 63.245.164.72 (talk) 07:28, 5 May 2008 (UTC)[reply]

Hello!

This bot has detected that this page contains an image, Image:Skin.jpg, in a raster format. A replacement is available as a Scalable vector graphic (SVG) at File:Skin.svg. If the replacement image is suitable please edit the article to use the vector version. Scalable vector graphics should be used in preference to raster for images that can easily represented in a vector graphic format.

Epidermis means hair in Simspons

[edit]

Someone should mention that Nelson from the Simpsons wrongly states that epidermis means hair in the episode "Bart of Darkness" —Preceding unsigned comment added by 90.198.167.137 (talk) 18:38, 19 August 2009 (UTC)[reply]

"terminally differentiated stratified squamous epithelium"

[edit]

No shit? Wikipedia is not a medical encyclopedia - these terms should be explained or left out. --AndersFeder (talk) 21:40, 4 December 2009 (UTC)[reply]

Number of layers

[edit]

.05 mm to 1.5 mm thick but 4-5000000 layers? 67.243.7.245 (talk) 15:51, 29 January 2010 (UTC)[reply]

Organogensis section is not clear

[edit]

Perhaps I am ignorant of the way things are referred to in biology, but I think that the description is somewhat confusing.

It states:

This inner layer is a germinal epithelium that give rise to all epidermal cells. It divides to form the outer spinous layer (stratum spinosum). The cells of these two layers, together called the Malpighian layer(s) after Marcello Malpighi, divide to form the superficial granular layer (Stratum granulosum) of the epidermis. [9]

So when the germinal epithelium "divides" to form the stratum spinosum, does it continue to be the germinal epithelium too? The word "divides" implies more than one thing produced.

The product of division is then referred to as "the cells of these *two* layers. What are those two layers?

The "two layers" "divide" (again) to form the stratum granulosum. Again, what is the other side of the division.

In the end, according to the picture of the different layers of the epidermis, there should be a basale, spinosum, and granulosum stratum. Would it be clearer to say that :

the germinal epithelium divides to form the basale and spinosum strati, and the spinosum further separates and differentiates to produce the stratum granulosum.


It is also not completely clear to me how this section relates to the section Cellular Kinetics. That section states that cells form at the stratum basale, take two weeks to reach the stratum granulosum, and then a further 4 weeks to reach the outler layers of the stratum corneum. However, in this section, it seems to imply that keratinocytes are formed in the stratum granulosum, not the stratum basale. Perhaps a diagram showing the names, origins, and dynamics of the different cells would help. —Preceding unsigned comment added by 131.215.220.164 (talk) 04:18, 22 March 2011 (UTC)[reply]

Keratin localization

[edit]

Keratinocytes produce keratin. This keratin accumulates in the epidermis but is it intracellular keratin or extracellular? I think it is intracellular but the article states this: "Differentiated keratinocytes secrete keratin proteins which contribute to the formation of an extracellular matrix". --Miguelferig (talk) 19:55, 8 August 2012 (UTC)[reply]
