quadriceps
Generates most of the force needed to produce the action.
prime movers : muscle that initiate a particular movement synergism : muscles that have the same action of the prime mover antagonist : muscles that come into play to oppose a certain movement
Generates most of the force needed to produce the action.
A muscle that assists the primary mover or Agonist
primary mover
Some of the synergist muscles in the human body are the masseter, temporalis, supraspinatus, and the extensor digitorum. Examples if the antagonist muscles are the flexor digitorum superficial is, triceps brachii, extensor carpi radials longus, and the internal intercostals.
A prime mover is the muscle that has the most influence in one direction on the joint it acts on. For example the prime mover in extension of the forearm is the triceps.

antagonist
Do you mean flexion and (abd)uction?? If so, the prime mover would be the deltoid muscle with many smaller muscles assisting. If you are in fact meaning flexion and adduction, the prime mover would be the pectoralis major and the latissimus dorsi with many smaller muscles assisting.
biceps brachii
The synergists.
