The Diaphragm.
Prime mover is the bicep and the antagonist is the tricep.
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.
A synergist muscle helps a prime mover muscle in creating a specific movement. It assists the prime mover by reducing unnecessary movements and helping stabilize the joint. Synergist muscles work together to produce coordinated movement.
An immobilization of the origin of a prime mover would prevent the muscle from contracting and generating movement. This can be due to injury, neurological impairment, or structural damage, and would result in limited or no function of the muscle. Rehabilitation and therapy may be required to restore movement and function.
Quadricepts
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.
the prime mover is the muscle responsible for most of the movement in a group of muscles; called the chief muscle.
Antagonist: Controls movement, opposite of prime mover Prime Mover: Main muscle that is directly responsible for movement Synergist: Aids in movement of muscle
Prime mover is the bicep and the antagonist is the tricep.
An agonist (prime mover)
Prime mover in medical terms means the muscle that is mainly responsible for a given motion.
a prime mover is the main muscle that causes movement. In the case of the hip flexion, the prime mover would be the rectus femoris or the ilopsoas
antagonist
The Gastrocnemius (calf muscle) is the primary mover. The Synergist (or assistor) muscle is the Soleus.
An antagonist muscle reverses the action of a prime mover. When the prime mover contracts to produce a movement, the antagonist muscle relaxes to allow that movement to occur in the opposite direction. This coordination between prime movers and antagonists is essential for controlled and coordinated movement.
The fixator of a muscle stabilizes the muscle at the point of origin.
