Talk:Lateral pterygoid muscle

Untitled
What happens to make the lateral Pterygiod spasm - moving my jaw to a cross bite and end-to-end?

Jaw opener?
I've been told numerous times by a Professor of oral biology that the Lateral Pterygoid is not a jaw opening muscle. In that it doesn't actively contract to open the jaw, it merely acts during the process of opening, started by "true" jaw openers such as the Anterior Belly Of the Digastric muscle, the Mylohyoid and the Geniohyoid muscles 82.41.101.178 (talk) 20:51, 8 December 2007 (UTC)

Not 1 but 2 muscles
Please, consider this - the heads of this "muscle" have different start and end as well as - what comes out of what I've just written - different function. That's why today physicians say they are 2 muscles. Not upper and lower head but Upper lateral pterygoid and Lower .... If only I translated it properly from Polish. Latin is: Musculi pterygoidei laterales superior et inferior, I think. Vinne2 (talk) 23:49, 3 November 2010 (UTC)
