Would a muscle that is long and thin (ie: more series elements than parallel elements) or a muscle that is short and thick (ie: more parallel elements than series) be able to lift an object that has more mass? Why?
The strength of the response of the entire muscle is determined by the number of motor units activated. The minimum unit of contraction is called the motor unit. ...
This solution describes the striations seen in muscles. With different striation patterns there is a difference in the amount of work that can be done. This solution also suggests some further reading in case you would like to expand the discussion of this problem.
