Positions of actin and myosin molecules in sarcomere

Name the positions of actin and myosin molecules in sarcomere before and throughout the muscle contraction?

E

Expert

Verified

Schematically actin filaments joined perpendicularly to both sarcomere extremities (that is, longitudinal sides) build contact with myosin filaments located in the middle of sarcomere and in parallel to actin filaments.
Prior to the contraction, the sarcomeres are extended (or relaxed) as the contact among actin and myosin filaments is merely made by their extremities. Throughout contraction actin filaments slide all along the myosin filaments and sarcomeres shorten.
