Which of the following would be recruited later in muscle stimulation when contractile strength increases?

Question

Quizplus · Accepted Answer

Motor units with larger, less excitable neurons would be recruited later in muscle stimulation when contractile strength increases. This is due to the size principle of motor unit recruitment, which states that smaller motor units are recruited first, followed by larger motor units as more force is needed. Larger motor units have larger neurons with higher thresholds for activation, making them less excitable and recruited later in the process.
