D) recovery
E) recruitment

Question

Quizplus · Accepted Answer

Complete tetanus occurs when the stimulus frequency is so high that the muscle fiber cannot relax at all during the contractions. This leads to a sustained contraction with no relaxation phase. A twitch is a single, brief contraction and relaxation cycle. Incomplete tetanus occurs when the stimulus frequency is high enough that there is partial relaxation between contractions but not complete relaxation. Recovery refers to the period of time it takes for a muscle fiber to return to its resting state after a contraction. Recruitment refers to the process of activating more motor units to create a stronger contraction in a muscle.
