Understanding Antagonistic Muscle Pairs

What is the primary function of antagonistic muscle pairs?

• To push bones away from each other

• To stabilize the body during movement

• To create opposing movements around a joint

• To increase muscle mass

Which muscle pair allows for opposite movements at the elbow?

• Gastrocnemius and tibialis anterior

• Quadriceps and hamstrings

• Biceps and triceps

• Deltoid and latissimus dorsi

In muscle movement, what is the role of the agonist?

• To relax and allow movement

• To produce the most force and cause movement

• To assist the antagonist

• To stabilize the joint

What is another term sometimes used for the agonist muscle?

• Prime mover

• Opposing force

• Secondary mover

• Stabilizer

What is the role of a synergist muscle?

• To stabilize the origin of the agonist

• To assist the agonist by adding force

• To prevent movement

• To oppose the agonist

Which muscle group acts as a fixator during a bicep curl?

• Gastrocnemius

• Rotator cuff muscles

• Hamstrings

• Quadriceps

What is the role of fixator muscles in movement?

• To stabilize the origin of the agonist

• To assist the antagonist

• To increase muscle size

• To create movement

During knee flexion, which muscle group acts as the agonist?

• Gluteals

• Gastrocnemius

• Hamstrings

• Quadriceps

In elbow flexion, which muscle acts as the antagonist?

• Biceps brachii

• Triceps brachii

• Brachialis

• Brachioradialis

Which muscle acts as a synergist to the biceps during elbow flexion?

• Triceps brachii

• Deltoid

• Brachialis

• Latissimus dorsi
