Removed

Removed a few factual inaccuracies, such as "Currently, it is thought that most of the CSF leaves the ventricular system via a path along the olfactory tracts and leaves the cranium through the cribriform plate." Note: the olfactory tracts are part of the olfactory system. They do not communicate with the ventricular system and have absolutely no role in CSF-passage. CSF is reabsorbed into the venous system (superior sagittal sinus) via arachonoid granulations - this fact is supported by hundreds of references. The removed sentence resembles rather a description of the olfactory pathway, with the olfactory nerve fibers entering the skull through the cribriform plate of the ethmoid bone.

Added a few more anatomic details, a reference, and links to two localized versions of Wikipedia. DrFlo1 | Talk 19:36 (EDT), May 26, 2005

This is a mess all right. I started trying to clean it up, but now I'm thinking I should just rewrite it from scratch. dsws 05:06, 14 December 2005 (UTC)[reply]

Cleanup

The "more information" section at the bottom is very poor style. I don't want to risk screwing something up as I know nothing about neuro. --aciel 19:35, 14 October 2005 (UTC)[reply]

User:Wee Jimmy cleaned this article up pretty substantially in December [1]. I've made some factual corrections just now and have removed the cleanup tag. --David Iberri (talk) 19:14, 6 January 2006 (UTC)[reply]

removed/reorganized listing of cerebral aqeduct as 'ventricle'.

Objected to cerebral aqueduct being listed as 'ventricle'. Thought compromise was to list ventricles, than interconnecting channels, although technically interventricular foramina are part of lateral ventricles [per Terminologia Anatomica]. Corrected/added with links major locations (cerebrum, diencephalon, midbrain, hindbrain) of parts of ventricular system to give sense of its interconnectivity within the brain (and spinal cord), as well as classification of individual parts of ventricular system as also parts of these (e.g., lateral ventricles including interventricular foramina as part of cerebrum, 3rd ventricle as part of hypothalamus of diencephalon, cerebral aqueduct as part of midbrain/mesencephalon, 4th ventricle as part of pons of hindbrain -all according to TA), without being (too) definitive about it.Jauntymcd 20:40, 25 March 2007 (UTC) Italic text[reply]

Walls of Ventricles?

Do the ventricles have walls, with any structure like arteries have structures (layers of materials & cells) for their walls? I see that the ventricles are lined with ependymal cells, but what I'm asking is if those ependymal cells are part of the walls of the ventricles, or if the ependymal cells are all there is.

I dont think so - it is just cavities where you want the fluid to be able to circulate and be able to reach all parts of the brain to rinse clean the protein wastes that build up between brain cells during waking hours and can become harmful if not clean rinsed away. Also when you look at the subarachnoid space - the interval between the arachnoid membrane and the pia mater - is occupied by delicate connective tissue trabeculae and intercommunicating channels containing cerebrospinal fluid (CSF). Also, wouldn't it be like asking if urine or the intra spinal fluid had walls limiting it? SvenAERTS (talk) 06:56, 24 February 2020 (UTC)[reply]

Amazing Fast fMRI video revealing waves cerebrospinal fluid flows into the sleeping brain during NREM sleep phase

During non-REM sleep, blood flows out of the brain just before a wave of cerebrospinal fluid rolls in, help cleaning proteins products out of the brain. Video: Laura Lewis, N. Fultz et al/Science 2019 https://www.youtube.com/watch?time_continue=15&v=eEszNmVFFm4&feature=emb_logo Maybe we can add it to some See also section?
