Does anyone know if the supraoptic nucleus of the hypothalamus synthesizes only ADH or also oxytocin? What about the paraventricular nucleus - does it only synthesize oxytocin? I've seen mixed answers on the web.

"supraoptic nuclei produce ADH and paraventricular nuclei produce oxytocin"

Wikipedia might quote not mainstream research. Stick with one each.

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!

Can someone clarify part V of The Nervous System (Peripheral Nervous System-neuroganglia)? Do I just need to know what a ganglion is or are there specific ones to know throughout the PNS? Also for Spinal Cord organization is it necessary to memorize all the spinal cord tracts (eg. dorsal column–medial lemniscal pathways, spinothalamal/cerebellar pathways)?

I doubt you need to memorize specific tracts. You'll likely never come across more than one question here or there on anything super specific, even at states/nats.

But hey, if you like studying about that, do it for fun! But, from an efficiency standpoint, I wouldn't start studying about those until nationals, at the earliest, keep it on my reference sheet for state.

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The 3rd edition is probably quite outdated...I'm on the 9th edition lol.

For neuroganglia in part v, do we just need to know the types of neuroganglia and what they do, or are there specific ones to know? I have parasympathetic and sympathetic ganglia right now.
