Talk:Sternocleidomastoid muscle

Untitled
"It also acts as an accessory muscle of inspiration, along with the scalene muscles of the neck." HUH? What's that mean? What is a "muscle of inspiration" - and how is this an accessory? --76.177.33.26 (talk) 10:10, 22 March 2010 (UTC)

RESPONSE:: This means that this muscle is not primarily used in breathing in, but is used to expand the ribcage further in forced inhalation (taking a deep breath). The scalene muscles of the neck do the same thing in deep breaths, they force the ribcage to expand. Hope this helps — Preceding unsigned comment added by Selizabethg (talk • contribs) 20:24, 31 January 2011 (UTC)

Problems with this muscle
I have a friend who is getting a surgery done relating to a abnormality in this muscle which was present at birth. I would like to see a section on common problems, but there is none right now.  Blue Rasberry  18:05, 24 September 2010 (UTC)

I like to add a comment, to this comment above. I had an issue with my collarbone and shoulder that presses on this neck muscle once in a while. When it does, I get occipital neuritis which is the same sidle of my head feeling numb and electric "pin pricks" and it is tiring, I have to rest when it happens. I can trigger it by tapping on this neck muscle also. It's one problem that I hope someone with add here to this article. — Preceding unsigned comment added by 66.26.112.243 (talk) 22:43, 18 May 2017 (UTC)

Extending the head?
Don't the sternocleidomastoid muscles pull the chin down, therefore flexing?--78.146.175.222 (talk) 00:43, 14 February 2013 (UTC)

Cultural references
The reference to Tom Wolfe's novel describes a man 'fan[ning] out' his neck by activating his sternocleidomastoid muscles. I've not read the source material but this seems to be describing the activation of platysma. I suspect this reference may be better suited the article on that muscle.

 * Some quick googling reveals that Wolfe explicitly refers to the sternocleidomastoid. This seems fairly plausible; at least one of my acquaintances (an ex-swimmer) has well-developed sternocleidomastoids which stand out quite distinctly beneath the platysma.
