"Facts

The masseter is the only muscle in the human body that is actually bullet proof. Any other sort of weapon can cause injury to the muscle, but bullets will bounce off."

Makes your dick as hard as a rocket ship.

Masseter and Platysma

Do we have a citation for the masseter - platysma antagonist link? I'm not sure this is correct. Cmungall (talk) 22:49, 5 March 2014 (UTC)

Yes, apparently so: [2] — Preceding unsigned comment added by 188.29.82.148 (talk) 23:49, 5 March 2014 (UTC)

No wait, that source may have just copy pasted from Wikipedia... " Boundless works with subject matter experts to select the best open educational resources available on the web, review the content for quality, and create introductory, college-level textbooks designed to meet the study needs of university students." I will look in Gray's, if that doesn't support this suggest remove it until a source can be found. — Preceding unsigned comment added by 188.29.82.148 (talk) 23:51, 5 March 2014 (UTC)

I did not find any support for this statement in Gray's. Masseter elevates the mandible with some protrusion due to its obliquity. Another anatomy textbook tells me that platysma's only action is to "wrinkle the skin of the neck", which doesn't sound that useful an action. I recall an old professor once told us that platysma is also used to make "tassels" rotate in opposite directions, but then I never heard that anywhere else and it may have just been a joke. In reality, platysma is an evolutionary remnant of the panniculus carnosus, the complete sheet of subcutaneous muscle present in some other animals, e.g. herd animals, can contract to dislodge flies from anywhere on their body without any major effort. In humans, it has no real action, and probably does not act on the mandible significantly even it does attach to the lower border. Due to lack of sources, and simple reasoning htat platysma is not a strong muscle compared to the chunky pterygomasseteric sling, I have removed the detail that masseter and platysma are antagonistic.

Here is another that has likely copypasted from Wikipedia:[3] since the publisher http://www.mobilereference.com/ is listed here as a Wikipedia mirror: Wikipedia:Mirrors_and_forks/Mno#MobileReference. It is a bad sign when the first page of Google hits is either irrelevant or mirrors. Looks like another "Wiki truth cycle", falsehoods become truths through people citing Wikipedia, then Wikipedia cites those sources in turn. — Preceding unsigned comment added by 188.29.82.148 (talk) 00:20, 6 March 2014 (UTC)
