Given two muscles of equal mass,a short,thick muscle and a long,thin muscle,one would expect the short,thick muscle to
A)contract with a greater force.
B)have its sarcomeres arranged in series rather than parallel.
C)shorten faster and further,but generate less force.
D)all of the above

Question

Quizplus · Accepted Answer

A short, thick muscle contains more myofibrils per unit of cross-sectional area, resulting in a greater force of contraction. The arrangement of sarcomeres in series or parallel does not directly affect force production. The ability to generate force is related to muscle size and architecture, rather than the speed or distance of shortening. Therefore, option D is not correct.
