I recently asked for information of thyroid function in another newsgroup and
I was reffered to a site dedicated to the thyroid. This site might hold the
information you are looking for. It is
www.thyroidmanager.org/thyroidbook.htm is is titled the thyroid and it's
diseases.
If this text dosn't contain the info you need then the main site ie
www.thyroidmanager.org contains many links on thyroid function.
Hope it helps
