Talk:Subclavius muscle

Untitled
this page dedicated to vestigal structures claims that this muscle is vestigal.... https://notes.utk.edu/bio/greenberg.nsf/0/0765bb50d404455385256f0000680854?OpenDocument&Click= SUBCLAVIUS MUSCLE This small muscle stretching under the shoulder from the first rib to the collarbone would be useful if humans still walked on all fours. Some people have one, some have none, and a few have two.

can anyone confirm this?Brallan 15:37, 20 December 2006 (UTC)

I've come across that page before as well. To the best of my knowledge though, this muscle is not vestigial. I've never seen a mention of this in any anatomy text I've come across. As well, it has some well-defined functions, such as stabilizing the sterno-clavicular joint when excessing pulling forces are places on the arm. I'm assuming this would be quite useful when hanging from things, or somewhat more relevant to present times, things like tug-of-wars, etc. In general, my understanding is that it has a stabilization function in most movements of the upper arm.

As such, based on my knowledge, I wouldn't say it's vestigial, as it still seems to serve some purpose in humans. —Preceding unsigned comment added by 130.179.255.239 (talk) 20:04, 17 January 2009 (UTC)


 * Agree, this muscle is not "vestigial", and it has apparently useful function(s).--Yahia.Mokhtar (talk) 15:38, 2 September 2016 (UTC)
