message: (02/13/09)
I have replaced the simple columnar of the prox. and dist. convoluted tubules with simple cuboidal. I have done this because all textbooks I have checked refute the original statement. In particular, I referenced the Colour Textbook of Histology, Elsevier, 2007 pp458. I think this is a minor change & one well supported by evidence. Welcome to other opinions.  —Preceding unsigned comment added by 121.44.159.135 (talk) 04:30, 13 February 2009 (UTC)
thread_title: Swapping columnar for cuboidal- thoughts

message: (Discussion topic added on 13/10/08)
shall we add some photos to give clearer ideas of the followings?
1.1.1 Squamous
1.1.2 Cuboidal
1.1.3 Columnar
1.1.4 Transitional
here may be a website that helps:

thread_title: Adding microscopice photos for content 1.1

message: Just a quick note to say that the opening sentence strikes me as rather odd, since it conflates epithelium with endothelium. I didn't edit it, however, since I'm not a biologist. Nevertheless, since the prefix of one glosses as "inside" (as in endoskeleton, the sort of skeleton us humans have), while the other glosses as "above" or "over" (as in the epicenter of an earthquake, meaning the ground-level center located above the underground, actual, center of techtonic movement), it seems wrong to me. And, since people use this encyclopedia for school-related research, it seems worth a mention. Someone with the relevant expertise ought to remedy this. Buck 04:17, 23 January 2006 (UTC)

text: It was utterly wrong. Epithelium of the viscera is still epithelium! Endothelium is completely different. JFW | T@lk 08:27, 23 January 2006 (UTC)

text: Endothelium must fall into one of the four tissue types: muscle, neural, connective, epithelial.  So is it not epithelial tissue?--Drewlew 05:14, 12 April 2006 (UTC)

text: The terms "epithelium" and "endothelium" are counterintuitive, I agree.  However, the article is correct -- there is no conflation of terms.  The confusion arises from the difficulties of anatomical orientation at various levels in a convoluted body plan.  Endothelium is "endo" because it's on the "inner" surface of the blood vessel or heart chamber, i.e. it forms the boundary with the lumen of the structure.  So in terms of gross body structure, this is the "deepest" you can get.  But histologically, it's still epithelium based on its characteristics.  Anyway, if it helps you, at the level of the tissue layers it's more natural to think of the layer with a free surface as being the most superficial, i.e. "epi".  --Mark Lundquist 15:38, 16 August 2006 (UTC)
thread_title:  epi- vs. endothelium 

message: I've reworded the desc for Squamous cells slightly.  The original didn't read quite right:
:The one-cell layer of simple squamous epithelium that forms the alveoli of the respiratory membrane, and the endothelium of capillaries, and is a minimal barrier to diffusion.
Wasn't sure if it meant "A one-cell layer...forms...capillaries, and is a minimal barrier..." or "The one-cell layer...that forms...capillaries, is a minimal barrier...", I went with the former.

thread_title:  Shape/Squamous desc 

message: I think this article needs a significant work-over because it defines epithelial tissue in terms of its omnipresent appearance as a thin layer of cells either one cell thick (simple) or several layers thick (stratified).  This does not provide a definition which can encompass glandular epithelium.

thread_title: general characters of epithelial tissue

message: I think the link to mesothelium is misplaced. The lining of the heart is called the endocardium and is composed of endothelial cells similar to those lining the arteries. The mesothelium, as it's Wiki page says, forms the lining of body cavities like the pleura, the peritoneum and the pericardium. The last of these is near the heart, but not in the heart.
