An EMG (electromyogram) measures electrical activity in skeletal muscle only in any type of muscle in cardiac muscle only in skeletal and smooth muscles only
Qbs E.
Motor unit recruitment: Is the activation of motor units based on the strength needed to perform a task. It proceeds from large to smaller motor units. It is an all-or-none phenomenon. It is not always the same for every muscle action. What does EMG measure? EMG measures the strength of muscle contraction. EMG measures the number of MU recruited. EMG measures electrical signals on the skin. EMG measures the voltage produced by muscle contraction. EMG measures both C and D. 3. In which fiber type will the contraction phase of a muscle twitch be shorter? a. Type I b. Type II
