Of all the muscles contracting simulataneously, the one that is mainly responsible for producing a particular movement is called the prime mover for that movement. The other muscles that help in producing the movement are called synergists. As prime movers and synergists muscles at a joint contract, other muscles, called antagonist muscles, relax.When antagonist muscles contract, they produce a movement opposite to that of the prime movers and their synergist muscles.

How does an antagonist differ from a prime mover?
An antagonist is a muscle that opposes the action of another muscle, while a prime mover is a muscle primarily responsible for producing a specific movement. In other words, antagonists work against each other to create movement, while prime movers are the key muscle groups that initiate and drive the movement.
How can a prime mover also be consider a antagonist?
A prime mover, or agonist, is the primary muscle responsible for a specific movement, while an antagonist opposes that movement. In certain contexts, a muscle can act as both a prime mover and an antagonist, depending on the movement being performed. For instance, during a bicep curl, the biceps are the prime movers for elbow flexion, but they can also act as antagonists when extending the elbow, helping to control the movement and stabilize the joint. This dual role is essential for coordinated and smooth muscle function during dynamic activities.
What muscle raises the heels off the floor?
The gastrocnemius and the soleus are the prime movers, but the tibialis posterior also assists
When any specific movement is performed the muscles that act directly as prime movers to perform that movement are called what?
The agonist muscle
When any specific movement is performed the muscles that act directly as prime movers to perform that movement are called?
The agonist muscle
When was The Prime Movers - Michigan band - created?
The Prime Movers - Michigan band - was created in 1965.
What reverses the action of a prime mover?
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.
One of the prime movers for flexion at the hips?
The prim mover for hip flexion is the Rectus femoris. This is a quadricep muscle that crosses the hip joint.
What is a spurt?
A spurt muscle is one that has an attachment, called the insertion, close to a joint. This allows them to be the main movers, usually referred to as prime movers. An example of a spurt muscle is the biceps in your upper arm, also called the bicep brachii.
What does antagonist mean when it comes to a muscle?
when one muscle is against and opposes another muscle
Which muscle opposes the gastrocnemius?
The tibialis anterior
What muscle opposes the deltoids?
Pecs and lats
