They control the passage of materials through body openings.

Question 18

Which of the following is TRUE regarding the voluntary control of skeletal muscle?

Accepted Answer

It is under conscious control via the somatic nervous system.

Question 19

Which of the following is a multi-step process that occurs during muscle contraction?

Accepted Answer

Calcium ions bind to troponin, tropomyosin shifts, myosin binds to actin, and ATP is hydrolyzed.

Question 20

Which of the following best explains why skeletal muscle tissue is essential for maintaining body temperature?

Accepted Answer

Muscle contraction generates heat as a byproduct of ATP hydrolysis.
