[edit] I
I wish to quote this article in my school science essays, but I doubt they will accept Wikipedia as a valid reference. Can you give me the names of some authorative books which I can cite as sources for what I write about the nature of Schwann Cells?
[edit] what about non-myelinating schwann cells?
this article does not discuss non-myelinating schwann cells, and may lead people to believe that all schwann cells myelinate axons, whereas this is not the case:

my e-mail is davidyaron@gmail.com for comments.
[edit] Images
I've reworded the article slightly, and intend to add some sources when I have the time. I've also tired to upload an image, but I'm not sure how to put it in the article - it's here http://en.wikipedia.org/wiki/Image:Schwann.JPG . I made the image in 3dsmax and added the labels with photoshop, so if anyone suggests any changes I could make to it, let me know and it shouldn't be a problem. Hbdgaz 00:41, 13 December 2005 (UTC)
[edit] length of Schwann-cell myelin sheaths
In Biological Psychology, 3rd ed by Rosenzweig, Breedlove & Leiman - page 35 - says that Schwann cells rarely cover more than 200 MICRONS i.e. .2 milimeters (article states one milimeter).
From the same: p 40-41, diagrams show perepheral nervous system axons in the human body. Unless someone can come up with a reference on that my impression is that there are axons that run from the base of the skull as far as the length of the spinal column, talk to other neruon there (preganglionic axons), which in turn talk to cells in the ganglion, the axons of which may run the length of a limb. Thus a 2 meter tall human would not have any 2 meter long axons. If axons ran the length of the entire human body, there would be no difference between the central nervous system and peripheral nervous system. Most mammals and vertebrates would have a similar neural arrangement (the book specifies that mammals have myelin, invertebrates do not, but does not talk about myelin in avians or reptiles for example).
Because myelin is found on axons in vertebrates, and vertebrates don't have axons running the length of the body, I'm removing the reference in this article to the fact that sometimes axons that are myelinated run the length of the body. Some invertibrates may have axons that run the length of their body. That is shown in the chapters on evolution, where differences are explained and validation for study/research & experiments with other critters is discussed. Vertebrates don't have myelinated axons (p165), and I doubt they have Schwann cells, but that's not my forté.
I am making corrections to the article and adding the reference. The Crisses 02:41, 19 December 2005 (UTC)
