Muscular System Quiz

What specific aspect of the muscular system is discussed in the document?

• Chronic responses

• Acute responses

• Long-term adaptations

• Genetic factors

What is the role of an agonist muscle?

• Muscle that contracts to produce movement

• Muscle that relaxes to allow movement

• Muscle that supports the movement of the joint

• Muscle that stabilizes the body

Which muscle is required to relax on the opposite side of a joint?

• Agonist muscle

• Antagonist muscle

• Synergist muscle

• Stabilizer muscle

What is the function of synergist muscles?

• To contract and produce movement

• To relax and lengthen

• To support the movement of the joint

• To stabilize the body

What is the characteristic of concentric muscle contraction?

• Lengthening of muscle length from resting state

• Shortening of muscle length from resting state

• No change in joint angle or muscle length

• Speed of contraction is controlled throughout the full range of motion

Which type of muscle contraction involves no change in joint angle or muscle length?

• Isoinertial

• Isokinetic

• Isometric

• Concentric

What is a key feature of isokinetic muscle contraction?

• Muscle lengthens from resting state

• Tension develops with no movement

• Speed of contraction is controlled throughout the full range of motion

• Muscle shortens from resting state

What is another term for isoinertial muscle contraction?

• Isometric

• Isotonic

• Isokinetic

• Eccentric

What are acute responses?

• Long-term changes in the body

• Immediate, short-term changes when we start moving/exercising

• Changes that occur only during sleep

• Permanent changes in the body

How long do acute responses last?

• For a lifetime

• Only during sleep

• Only for the time we are moving/exercising and a short time afterwards

• For several months
