Fascicle correct answers Bundles of muscle fibers Epimysium correct answers Protective (bones, joints) fibrous sheath and continuation of fascia. Perimysium correct answers Groups bundles or fascicles Endomysium correct answers Protective sheath between muscle fibers Myofibrils correct answers Hundreds, thousands of parallel threads that lay parallel to form muscle fibers.

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...
