Is it "trophic" or "tropic"? You use both in the same pararaph. Jeff Knaggs 22:48, 21 November 2005 (UTC)[reply]

i think my teacher told us that tropic is different from trophic..

yes, i think my teacher told us that tropic is different from trophic?

Tropic refers to something that "goes to" or "tends towards". Trophic refers to "eating" something (what is used for nutrition. The correct word here is tropic, because the first hormone goes to a second endocrine gland. There are several other incorrect uses of trophic to refer to tropic hormones.

Tropic Versus Trophic

According to multiple dictionaries (such as Merriam-Webster), trophic and tropic are the same. Many of these words are related in similar ways between British and American English as well. ie. thyrotropin vs. thyrotrophin. It may be the source for the discrepancy, in that there is no discrepancy.65.78.26.83 (talk) 03:15, 8 April 2009 (UTC)[reply]

I am removing the redirection of trophic to tropic because there IS a difference. Tropic is as the article describes and trophic is actually a hormone that promotes cell survival...like the neurotrophins --Mubinchoudhury (talk) 15:10, 7 May 2008 (UTC)[reply]

Moved following comments from main page to this page:

"Growth hormone is not in fact a tropic hormone as it does not meet the requirement of stimulating other endocrine glands. It is produced by the anterior pituitary."

This is incorrect; GH stimulates the release of IGFs from other organ tissues.

"Tropic hormones are actually produced by the hypothalamus."

This is wildly inaccurate. The anterior pituitary secretes hormones made by the anterior pituitary. Releasing hormones made by the hypothalamus control the release of these tropic hormones.

In either case both of the above comments did not belong on the main page. DrNixon 17:10, 2 March 2007 (UTC)[reply]

-Mubinchoudhury is confused. Tropic and trophic are the same thing. For those with a subscription, you can verify it at Encyclopedia Britannica's online article on pituitary hormones (http://search.eb.com/eb/article-72717): "the targets of certain hormones ... called tropic, or trophic, hormones, are other endocrine glands." 129.194.8.73 (talk) 12:05, 12 January 2009 (UTC)[reply]

Tropic act upon endocrine organs and Trophic act upon non-endocrine organs

No. Mubinchoudhury is absolutely correct and Encyclopedia Britannica's online edition is wrong. Look at any basic textbook on endocrinology and you will see that tropic hormones act on endocrine organs to regulate the release of other hormones whereas troPHIC hormones act on non-endocrine organs. As such, GH is a troPHIC hormone, not a troPIC hormone, as IGF is produced in the liver, which is not considered to be an endocrine organ. Redirecting from trophic hormone is inaccurate and I am re-removing it. 128.173.35.207 (talk) 22:55, 9 February 2011 (UTC)[reply]

I noticed my modifcations of trophic hormone have been reverted. You Wikipedia trolls are awful and counterproductive. So go ahead and continue to proagate incorrect information. And Wikipedia wonders why it is losing authors... 71.206.142.105 (talk) 11:18, 11 February 2011 (UTC)[reply]

Page 84 of this text lists GH as a tropic hormone. I've never seen the liver described as an endocrine gland, though. So, as constructed, the article is a bit confusing. Shootbamboo (talk) 01:17, 30 March 2011 (UTC)[reply]
