Muscle Function and Contraction Quiz

What is the function of an agonist muscle?

• To contract and cause movement at a joint

• To cause pain and discomfort at a joint

• To relax and inhibit movement at a joint

• To stabilize and support a joint

What is the function of an antagonist muscle?

• To work in the same direction as the agonist muscle

• To have no function

• To assist the agonist muscle

• To work in opposition to the agonist muscle

Which type of muscle function stabilizes the origin of the agonist muscle?

• Antagonist muscle function

• Extensor muscle function

• Synergist muscle function

• Flexor muscle function

What type of muscle contraction occurs when the muscle length remains the same?

• Isometric contraction

• Isotonic contraction

• Concentric contraction

• Eccentric contraction

Which type of muscle contraction involves the muscle shortening?

• Concentric muscle contraction

• Eccentric muscle contraction

• Relaxation muscle contraction

• Isometric muscle contraction

Which type of muscle contraction involves the muscle lengthening?

• Eccentric muscle contraction

• Cardiac muscle contraction

• Concentric muscle contraction

• Isometric muscle contraction

What is the main function of a fixator muscle?

• Stabilize the origin of the prime mover muscle

• Provide flexibility to the joint

• Increase the speed of muscle contraction

• Initiate movement in the opposite direction

Which type of muscle contraction is used in activities like holding a heavy object in a fixed position?

• Isokinetic contraction

• Isotonic contraction

• Isometric contraction

• Eccentric contraction

What is the primary function of an antagonist muscle?

• To relax and lengthen when the agonist muscle contracts

• To assist the agonist muscle in performing its primary function

• To provide support and stability to the agonist muscle

• To contract and shorten when the agonist muscle contracts

Which type of muscle contraction is used in activities like lifting a weight?

• Concentric muscle contraction

• Isometric muscle contraction

• Cardiac muscle contraction

• Eccentric muscle contraction
