Question

The contraction of a single muscle fiber can be divided into three stages: the period (time between stimulation and initiation of contraction), the period (when the muscle shortens), and the period (when the muscle returns to its former length). When the muscle is not allowed to relax completely between stimuli, occurs. The contractions gradually increase in intensity. When maximal sustained contraction is reached, is achieved. This stage will continue until occurs, and the muscle relaxes even though stimulation continues.

          The contraction of a single muscle fiber can be divided into three stages: the ____ period (time between stimulation and initiation of contraction), the ____ period (when the muscle shortens), and the ____ period (when the muscle returns to its former length).

When the muscle is not allowed to relax completely between stimuli, ____ occurs. The contractions gradually increase in intensity.

When maximal sustained contraction is reached, ____ is achieved. This stage will continue until ____ occurs, and the muscle relaxes even though stimulation continues.
