3a- Define optimal length of a muscle and (b) Explain what causes force of contraction to change with length.
Madhur L.
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.

Short Answer Explain, based on the structure of the muscle fibers, why skeletal muscles can contract but not lengthen.
