Question

when all nerve fibers are stimulated, and increase and stimulus strength will produce no ___ in muscle tension

Answer 1

When all nerve fibers are stimulated and an increase in stimulus strength produces no further increase in muscle tension, this is referred to as reaching **tetanus** or achieving a **maximum contraction**. Essentially, all muscle fibers are already activated, and the muscle has reached its maximum tension, meaning that additional stimuli won't increase the tension further.
