.. Masseter - prime mover of jaw closure - elevates the mandible ... External intercostals - with 1st rib fixed by scalene muscles - pull ribs toward one
the Masseter muscle is the prime mover of mandible

the masseter muscle
Suprahyoids!
An agonist (prime mover)
A muscle that assists the primary mover or Agonist
The primary mover.
Masseter
The muscle that is responsible for most of a movement is called a prime mover. It may also be called an agonist.
One is the agonist and the other is called the antagonist. Agonist: muscle which is the main mover, it contracts and shortens Antagonist: muscle that lengthens and controls e.g. flexion at the elbow: the biceps are the agonist and the triceps are the antagonist.
prime mover (agonist)Not sure what you're asking here, but the biceps brachii is the prime mover facilitating flexion at the elbow joint.
The primary movement is called the Prime mover or Agonist
Primer Mover (agonist)
If I'm not mistaken I believe that for this movement to happen there are two muscles that need to be used- because muscles work in pairs. For this particular movement I am sure that the Agonist muscle (prime mover), the muscle that relaxes, is the Bicep. And the Antagonist, the muscle that contracts, is the Tricep.
Muscles cannot push, they can only pull which means they work in pairs in order to move, this is known as antagonistic pairs. For example with a bicep curl you have the agonist/ prime mover (Bicep) and the antagonist/ Opposing muscle group (Triceps). As the agonist contracts it pulls the antagonist which relaxes.
