I've rolled back this change, largely because it is from an anon and with no edit summary. --Arcadian 13:15, 22 July 2006 (UTC)[reply]

Thanks, Arcardian. I had previously left this section alone even although I didn't agree with it (I believe I wrote the introductory bit which is more appropriate). However, as it stands it is incorrect. Our anonymous editor may be justified. The middle meningeal artery runs outside the dura, so a torn MMA causes an extradural hematoma. This is indeed extremely uncommon in infants. Extradural bleeding requires huge pressure and must therefore be arterial. Subdural bleeding requires only venous pressure and is therefore usually venous. I will rewrite. Preacherdoc 21:15, 22 July 2006 (UTC)Preacherdoc.[reply]

Thank you -- looks good now. --Arcadian 22:51, 22 July 2006 (UTC)[reply]

"pterygonal"?

Per this sentence: "It has three branches: the temporal, pterygonal and coronal branch." -- is "pterygonal" legitimate? It doesn't check out in Dorlands or PubMed, and most of the Google hits seem to be Wikipedia mirrors. --Arcadian 15:32, 23 July 2006 (UTC)[reply]

One of the problems with the public domain edition of Gray's is that terminology and nomenclature evolves with time. An example is the nerve we all call the radial nerve. My printed edition of Gray's (a cheap reprint of a "classic" edition) calls it the musculospiral nerve. The next problem is that my knowledge of the MMA isn't sufficiently detailed to know what the small branches are (even the diagram is of little help, showing only the origin of the MMA). The wikilink (as you've seen) for each branch is generic, and doesn't link to a specific branch of the MMA.

The best clue I can find is on this webpage, which suggests that the three largest terminal branches of the MMA are simply called the anterior, middle, and posterior (but it is clear that a lot of people, e.g. Adachi, have spent a lot of time thinking about it in a lot of detail!).

Sounds good. I certainly agree with you that Gray's content has many limitations, and it is important to confirm terminology with more modern sources, using TA where possible. These were the only four branches I could find with TA provided:

ramus orbitalis arteriae meningeae mediae - r_02/12691308 at Dorland's Medical Dictionary
ramus parietalis arteriae meningeae mediae - r_02/12691405 at Dorland's Medical Dictionary
ramus petrosus arteriae meningeae mediae - r_02/12691548 at Dorland's Medical Dictionary
ramus frontalis arteriae meningeae mediae - r_02/12690089 at Dorland's Medical Dictionary

For now, I've deleted the references to the branches we can't substantiate, but I wouldn't object to their reinclusion if we could find a reference. --Arcadian 17:41, 24 July 2006 (UTC)[reply]

That seems very reasonable. Another problem is (as that website suggests) that the arterial architecture varies widely between individuals (in some cases one individual may have a different structure on each side!). This means that the more you try to map a vessel and its branches, the harder the job becomes. TA may not exist for smaller branches since they may not be permanent enough to be officially named.Preacherdoc 21:03, 24 July 2006 (UTC)[reply]

Wikiproject Neuroscience

I have labelled the page under Wikiproject Neuroscience due to its clinical relevance to epidural haematoma. Diptanshu^Talk 09:48, 18 May 2013 (UTC)[reply]
