Would someone be able to explain what is going on in the diagram, in terms of antagonistic muscle action between muscles A and B when the mouth is opened and closed? Having trouble understanding exactly what happens.

I think I can sort of figure it out. This is what happens when the jaw opens:
Muscle A contracts and pulls on the nub of bone on the other side of the jaw joint pivot, causing the jaw, which is on the other side of the pivot, to open.
To close the jaw, muscle B contracts:
They're antagonistic because they cause opposite effects when they contract.Last edited by anosmianAcrimony; 05-03-2016 at 18:33.

I hope that makes sense.
