41. Explain the sliding filament model of contraction. Be sure to include your response comparing the relaxed and contracted sarcomeres of muscle fibers. 42. Explain how an action potential is generated, propagated, and terminated in skeletal muscles (starting from the nerve impulse to the restoration of ionic conditions).

Question 2. (Based on your Reading "Sliding Filament"). We have only known how muscle contracts for about 60 years. (I) Please describe briefly the main premise of the "Sliding Filament Theory". (II) Then explain how the new findings about titin have improved our understanding on how muscles contract. (10 pts)
