Pre-Lab Questions 1. How do banding patterns change when a muscle contracts? When a muscle contracts, the banding patterns within the muscle change due to the sliding filament theory of muscle contraction. This theory suggests that muscle contraction occurs when thin filaments (actin) slide over thick filaments (myosin), resulting in the overlapping of these filaments and shortening of the sarcomeres, which are the basic contractile units of the muscle. As a result, the dark A bands, which...
