Positions of actin and myosin molecules in sarcomere
What positions of actin and myosin molecules in sarcomere before and throughout the muscle contraction?
Expert
Schematically actin filaments affixed upright to both sarcomere extremities (and longitudinal sides) contact myosin filaments positioned in middle of sarcomere and in parallel to actin filaments.
Before contraction the sarcomeres are extended (relaxed) because the contact between myosin and actin filaments is only made by their extremities. Throughout contraction actin filaments slide along the myosin filaments and the sarcomeres shorten.
