[edit] Testosterone
I thought it was made on the Testicles...
- It is made by the testes and (to a lesser extent) by the adrenals. --David Iberri (talk) 23:21, 8 March 2007 (UTC)
[edit] zona fasciculata
The heading where it now says zona fasciculata previously said "your gay". I guessed at what the heading should be.
[edit] Cortical layers
I edited out the references to the zona glomerulosa and zona fasciculata because the context they were originally used in may have confused readers into thinking that the z. glomerulosa and z. fasciculata were the adrenal medulla and cortex (respectively). More importantly, the z. glomerulosa and z. fasciculata are really the top two of the three layers of the adrenal cortex (the third, and deepest, is the z. reticularis). Also, the adrenal glands are not part of the sympathetic nervous system proper. It is more accurate to say that they are innervated by, and respond to stimulus from, the sympathetic nervous system. In another maniacal editorial rampage, I edited out "endocrine gland" because all glands are part of the endocrine system.
- Sorry to interrupt, but all glands are not part of the endocrine system; some, such as sweat glands, are exocrine. --Diberri 01:52, Apr 7, 2004 (UTC)
As of now (Mon Mar 18 02:38:51 PST 2002), there needs to be some more deliniation and writing up of the anatomy of the different cortical layers, the role of angiotensin II, etc.).

[edit] Merge
I merged the adrenal cortex and adrenal gland articles per the request of USER:Kosebamse who wrote on my user page that having too many pages makes it hard to know what is in the encyclopedia. I don't agree, but i don't really care how it is, and I think I'll do it Kosebamse's way. I'll see if there are other articles I developed in too much detail and that could be merged with a master article. SoCal
[edit] Comparative anatomy
Some comparative anatomy and physiology would definitely fill a huge void in this largely anthropocentric article. --Diberri | Talk 01:21, Apr 13, 2004 (UTC)
[edit] Anatomy pic
Someone please add a picture of location in the body!! thx
- I added an image from Gray's Anatomy, but it doesn't highlight the adrenals particularly well. Hopefully someone can find a better pic. --David Iberri | Talk 22:03, Jun 23, 2005 (UTC)
[edit] Adrenal gland removal
Some emergencies require you to have your adrenal glands removed. How does that affect you? do the synthetic chemicals work as well, and what about the fight-or-flight response, is that basically gone?
- Adrenals are not typically the subject of emergency removal. The spleen is the usual suspect. Unilateral adrenalectomy (on one side) leads to a brief decrease in cortisol levels which may require some suppletion therapy. The fight-flight response does not disappear on bilateral adrenalectomy (there is still an autonomic nervous system left to serve this function), but it makes the patient dependant on hydrocortisone and fludrocortisone suppletion.

- Bilateral adrenalectomy is fatal unless the hormones are replaced artificially. This is primarily because the adrenal produces mineralocorticoids like aldosterone required for sodium, potassium and water homeostasis. The loss of cortisol production is also fatal over a longer period. In research adrenal glands are often removed from rodents when studying stress responses. In order to survive the animals must be given saline to drink. —The preceding unsigned comment was added by Povmcdov (talk • contribs) 12:57, 26 February 2007 (UTC).
[edit] Products of the Adrenal
I would be interested to see a journal reference for the statement that the zona fasciculata "have the same functions as cells of the zona fasciculata". The textbook view (for example, Junqueira and Carneiro, Basic Histology 11th ed) is that the z. fasciculata produces cortisol and the z. reticularis produces androgens.
- Thats what my source says too (lecture notes). Also the zona glomerulosa produces mineralocorticoids. Povmcdov 12:59, 26 February 2007 (UTC)
[edit] Sex Hormones or Steroids?
Are testosterone and estrogen considered steroids or hormones? My teacher says they are produced in the cortex, but it says here that only the catecholamines are produced in the cortex. My teacher said testosterone and estrogen are produced in the medulla. Which is right? Dan 07:54, 28 March 2007 (UTC)
- Testosterone, estrogen, etc. are all considered steroid hormones. Adrenal steroids are synthesized in the cortex while catecholamines are synthesized in the medulla. The article currently reflects these facts; where are you reading that "only the catecholamines are produced in the cortex"? That most certainly is incorrect.
