One of the primary characteristics of all muscle tissue is contractility, the ability to shorten (contract) and lengthen (relax). You've identified the various components of a myofibril above. Now, use the table below to indicate what occurs to each band, line, or zone when the muscle contracts vs. relaxes. What occurs to this region / structure during contraction/relaxation? Region / Structure A-Band H-Band I-Band M-Line Z-Line Zone of Overlap Sarcomere No change Shortens Lengthens Muscle Contraction Muscle Relaxation

Slow twitch muscle fibers are characterized by all of the following EXCEPT: O a) used in endurance type of activities O b) contract rapidly and forcefully Oc) resistant to fatigue O d) have a direct relationship to the oxidative energy system

In an isometric contraction, how can the muscle stay the same length when the muscle is contracting? Can choose more than one - The muscle is not able to generate more (or the same amount) force than the load, preventing shortening of the muscle. - Calcium stops entering the sarcoplasm when the desired length is reached. - Elastic elements of the muscle stretch in response to the contraction of the muscle, so that the muscle stays the same size despite shortening sarcomeres. - The myosin heads detach from actin when they reach the desired length.
