Anatomy & Physiology B/C

According to Human Anatomy & Physiology - 8th ed by Marieb and Hoehn, the supraoptic and paraventricular nuclei produce both ADH and oxytocin.
This is also supported by: http://www.ncbi.nlm.nih.gov/pubmed/10599731, which states "The hypothalamic supraoptic (SON) and paraventricular (PVN) nuclei consist of arginine vasopressin (AVP)- and oxytocin (OT)-synthesizing neurons that send projections to the neurohypophysis, whereas the PVN also projects to other brain areas".
These two sources seem pretty reliable to me. Hope this helps!

I have the same book as you, except the 3rd edition, and it says that OXT is produced by the PVN and ADH is produced by SON.

The 3rd edition is probably quite outdated...I'm on the 9th edition lol.

My book led me to top 10 at nationals, so I'm fine with the 3rd edition. (I got it for $2 at a book fair too )

I'm not suggesting your book is flawed/wrong, but maybe recent research has suggested that both nuclei produce both hormones, and the newer edition may reflect this.

Does anyone know when the training handout for anatomy will be posted on soinc.org?

How specific do we need to study? For example, do we need to know the difference between the different types of focal epilepsy and the different types of generalized epilepsy? And have MRI's of the abnormal brains of each disease?

Generally for a regional or state level test, I would expect not especially for Division B.

And have MRI's of the abnormal brains of each disease?

Though this may not necessarily show up on a test (although it technically could), it would be beneficial to know as it could help better your understanding of the effects of a disease.

nvm.

Hi,

You never know :O

Thanks,

Can anyone tell me if constriction of blood vessels is parasympathetic or sympathetic? I see different answers in different places..

I'm pretty sure that it's both. For example, the sympathetic nervous system will dilate the blood vessels that supply the skeletal muscles and heart (via B1 adrenergic receptors), as well as constrict blood vessels that supply visceral organs such as the intestines (via a1 adrenergic receptors). The parasympathetic nervous system will do the opposite via Ach rather than norepinephrine/epinephrine.
