Definition

I'm missing a short definition of cerebrum in the first sentence and/or disambiguation hatnotes. Is cerebrum a part of the brain, a synonym for brain or just the latin word for human brain? Isheden (talk) 16:37, 20 September 2013 (UTC)[reply]

 Done (not by me though). Lova Falk talk 16:12, 4 October 2013 (UTC)[reply]

I will be adding citations for the Structure and Function sections of this page. Changes should be minimal, unless I find inaccuracies in the information. Lehession (talk) 11:55, 21 January 2015 (UTC)[reply]

"Superior-most region"

The beginning of the article says that "the cerebrum is the superior-most region of the central nervous system". While, as a layman in this area, I do have an idea of what "superior-most" mean (my guess is "uppermost" in a standing human), I am not sure, and even when I followed the link to superior-most and tried to read what it said there, I still found no answer; I was actually just more puzzled (or confirmed in my uncertainty), as it says this:

"In Man, the directional terms "superior" and "inferior" essentially refer to this rostrocaudal dimension, because our body axis is roughly oriented vertically in the erect position. However, all vertebrates develop a kink in the neural tube that is still detectable in the adult central nervous system, known as the cephalic flexure. The latter bends the rostral part of the CNS at a 90 degree angle relative to the caudal part, at the transition between the forebrain and the brainstem and spinal cord. This change in axial dimension is problematic when trying to describe relative position and sectioning planes in the brain."

What I am left with is only an "essential" (non-complete) definition and a statement that it is "problematic", and I am still not sure if "superior-most" means "uppermost" or "frontmost" when talking about the brain or the nervous system.

This might mostly be a problem with the section "Orientation in neuroanatomy" in the neuroanatomy article (it is not very easy to read if you just want a quick answer for a human orientational term, as the article tries to be general for all animals), but it could also help if it was made clearer in this article, for instance by stating " (uppermost)" or " (frontmost)" after "superior-most".

I was also thinking about changing the "superior-most" link to refer to Anatomical terms of location#Superior_and_inferior instead, as it gives a more direct description of superior and inferior which leaves me 99% sure it means "uppermost" (or "uppermost in a standing human") in this case.

Can anyone medically educated (or anyone through a credible reference) clear the last 1% of doubt in me? Does superior-most mean uppermost in this case? --Jhertel (talk) 19:03, 3 June 2016 (UTC)[reply]

Hi Jhertel it can only mean uppermost in the context - unless somebody knows better! Have changed it. cheers --Iztwoz (talk) 21:11, 3 June 2016 (UTC)[reply]
