Talk:Medulla oblongata

There's a tuberculum cinereum in the medulla now is there?
From the current article:

>The lower part of the medulla, immediately lateral to the fasciculus cuneatus, is marked by another longitudinal elevation known as the tuberculum cinereum.

Correct me if I'm wrong, but is the tuberculum cinereum not in the hypothalamus? This was my understanding, and it is also this body that is referred to in the link.

As well:

>The base of the medulla is defined by the commissural fibers, crossing over from the ipsilateral side in the spinal cord to the contralateral side in the brain stem; below this is the spinal cord.

Again, I was under the impression that this is attempting to describe the pyramidal decussation. If these are also known as commissural fibres by some, then the linked-to article should at least be changed to something else, as it doesn't talk about the crossing of corticospinal fibres at all.

I'll take a look to see if there's any other glaring errors in this article when I have more time :) corvus.ag (talk) 23:30, 31 December 2008 (UTC)

Ascending tracts in the medulla
Good article. Studying it at the moment.

Ascending tracts (e.g. DCML / Spinothalamic) ascend through the medulla, no? So suggest add this to functions of the medulla?

Info that would be useful
If anyones interested in supplying it, I'd like to see this page include the following info: Related Disorders to the Medulla. Drugs which affect the Medulla. Primary neurotransmitters in the Medulla. Seg 02:45, 10 November 2005 (UTC)

The image
The sagittal MRI image does not indicate the correct location of the medulla oblongata - it is a little too caudal & actually indicates the most cephalad extent of the spinal cord. The medulla is anterior to the cerebellum and has the inferior cerebaellar peduncles arising from it, so the circle needs to move up a little, if anyone knows how to. --Mattopaedia 00:28, 26 January 2006 (UTC)

Question
What's the deal with being shot here? Is it true that this will cause to body to be completely immobile with no twitches? Are the movies right?


 * Which movie(s) are you referring to? Miami Vice or Waterboy? --WhiteEcho 20:28, 28 August 2006 (UTC)

Orneriness in Alligators
I removed "In reptiles, such as the alligator, it is credited with controlling functions such as orneriness." since as far as I can tell this is just a rearrangement of a quote from The Waterboy, not actual scientific information about the medulla oblongata.


 * I agree. Everyone knows that alligators are ornery because they got all them teeth and no toothbrush. Tracer Bullet 05:45, 9 February 2007 (UTC)

Clean up needed
Clean up, reference to autonomic nervous system and raphe nuclei needed. Miserlou 01:12, 18 December 2006 (UTC)

Unneccesary revert
There is no justification in that revert. Those were all legit and very sorely needed edits. Miserlou 02:41, 18 December 2006 (UTC)


 * I think this is just a matter of miscommunication because we were both editing the same article at the same time. Please take a closer took at the edit history. --Arcadian 03:38, 18 December 2006 (UTC)


 * Here is your edit from today (Dec 17th) with your edit summary "REVERT! I resent the implication that it was vandalism, it was cleanup, explained in edits and even mentioned in talk page. Look at this reasonably."
 * Here is where I said I was fixing the vandalism from December 12th. I'm assuming that is what you were responding to in your edit summary, but nobody was accusing you of vandalism.
 * Here was the vandalism on Dec 12th, where the word "arteries" was replaced with "butt cheeks".


 * Sorry dude. Physiological psych final tomorrow, getting all stressed and edgy on the internets.Miserlou 03:42, 18 December 2006 (UTC)


 * Inexcusable that information such as "buttcheeks" is still kept in the entry after such a period of time. The specific section on "Blood Supply" was better organised under Arcadian's edit. No edit wars please. Permafrost 07:13, 18 December 2006 (UTC)

I just want to point out that "butt cheeks" and "butt hole" appear to be vandalism in the section "Between the anterolateral and posterolateral sulci"Myocastor 15:12, 17 July 2007 (UTC)

Questioning "Effects on the Body" Section
Does the information supplied under that headline belong in there? I think it should have a different title.

What I gather from the section name is that it will tell me what effect medulla oblongata has on the body, not what shooting someone through the mouth to hit it will do to the person. This is amateurish. --WNF 08:35, 8 January 2007 (UTC)


 * I have removed the unsourced section on the medula's role in assassination. If anyone wants it back, please provide a source. --Arcadian 20:44, 24 January 2007 (UTC)

Military snipers are trained to shoot for the Medula Oblongata, because it instintaneously halts all motor functions. They call it the "chestnut", I think. The best shot, apparently, is either from the rear a at the base of the skull, or through the mouth. http://charlotte.creativeloafing.com/gyrobase/Content?oid=oid%3A2090 http://www.snipercentral.com/forums/viewtopic.php?t=4477&start=0 (65.4.245.192 06:36, 12 May 2007 (UTC))

changed XI to IX
I think it was a typo on line 37 which read

The posterolateral sulcus lies in line with the dorsal roots of the spinal nerves. It gives attachment to the rootlets of the glossopharyngeal, vagus and the accessory nerve or the XI, X, and the XI cranial nerves from above downwards in order.

which I changed to IX, X and the XI

Proposed merge with Pyramid (brainstem)
The term medullary pyramids is far more widely used and this page could easily be integrated with medulla oblongata (with its own section) which is in need of expansion. Iztwoz (talk) 18:12, 11 January 2015 (UTC)
 * I am leaning to oppose a merge... I think we should be careful when merging into a 'top-level' article about an organ like this. The danger is that if we merged all the relevant subarticles, we will make this into a list, and over time as edits are made we may actually lose some important information. I have also posted something at WT:ANAT about this. --Tom (LT) (talk) 20:52, 11 January 2015 (UTC)
 * ✅. Notability guidelines would offer more guidance on this situation and also, I think, offer more support to other mergers. --Tom (LT) (talk) 20:56, 11 January 2015 (UTC)
 * Page moved to Medullary pyramids and rm merge proposal.--Iztwoz (talk) 12:07, 24 February 2015 (UTC)

"See Also" Section...?
Other parts of the brain? Jobonki (talk) 17:16, 28 July 2015 (UTC)
 * Contained within the nervous system navbox. I'll change its state to expanded. --Tom (LT) (talk) 00:38, 29 July 2015 (UTC)

The medulla is not responsible for respiration and I have deleted references to it
In 2011 Dr Daniel Rubens showed that the vestibular system of the inner ear is responsible for the breathing impulse, and not the medulla. He did a study on mice by injecting gentamicin into their ears and found the mice with destroyed ears no longer responded to CO2 or breathed normally. He also concluded that sudden infant death syndrome was caused by inner ear damage for this exact same reason.

The article is hence heavily outdated so I have updated it to comply to new science. — Preceding unsigned comment added by 2.29.87.48 (talk) 08:03, 11 May 2018 (UTC)

Breathing
An IP editor today added the following material to the article: "There exists a popular medical myth even among doctors that the medulla oblongata is what regulates the CO2 induced respiration reflex, and was long believed to be true. In 2011, Dr Daniel Rubens, a researcher for sudden infant death syndrome (SIDS) concluded that the vestibular system in the inner ear is actually responsible for the breathing reflex, as laboratory mice with chemically-induced damaged inner ears did not respond at all to CO2 and did not increase their respiration rate. New research has shown that the vestibular system is crucial for the survival of mammals as it regulates respiration, and the medulla either plays very little role in regulating respiration, or not at all."

I reverted the changes because: (a) I'm pretty sure they are not correct. The vestibular system contributes to overall arousal, and loss of activity there could in some marginal situations lead to cessation in breathing, but to my knowledge there is no evidence that any of the crucial neural circuitry that directly controls breathing lies in the vestibular nuclei. As I understand it, the statements previously in this article were correct. (b) Even if I am wrong and the new wording is actually correct, Wikipedia policy requires that it be supported by a proper published source. See WP:MEDRS for a description of what counts as a proper source. Looie496 (talk) 14:49, 11 May 2018 (UTC)
