Muscular System Test

For the muscular system to operate, it depends primarily on which other system?

• skeletal

• endocrine

• nervous

• integumentary

Which connective tissue surrounds fasicles?

• epimysium

• endomysium

• perimysium

• mesomysium

Which connective tissue surrounds the whole muscle?

• epimysium

• endomysium

• perimysium

• mesomysium

Which connective tissue surrounds individual muscle fibers?

• epimysium

• endomysium

• perimysium

• mesomysium

Actin myofilaments are

• attached to the Z disk.

• are found primarily in the H zone.

• are thicker than myosin filaments.

• attached to the sarcolemma.

Which area of a sarcomere contains only actin?

• Z disk

• A band

• H zone

• I band

Which part of the sarcomere does not shorten during muscle contraction?

• A band

• H zone

• I band

• Z disk

How does the sarcolemma respond to the action potential?

• The sarcolemma depolarizes and propagates the action potential.
• The sarcolemma remains unchanged during the action potential.
• The sarcolemma contracts and relaxes immediately.
• The sarcolemma inhibits the action potential propagation.
• The sarcolemma absorbs the action potential without response.

What type of muscle is this?

• Skeletal

• Cardiac

• Smooth

• Intestinal
