Question 1

◦ increasing the stimulation up to the maximal stimulus
◦ recruiting small and medium muscle fibers
◦ increasing stimulus above the treppe stimulus
◦ increasing stimulus above the threshold
Question 2
Which of the following would be recruited later in muscle stimulation when contractile strength increases?
◦ many small motor units with the ability to stimulate other motor units
◦ large motor units with small, highly excitable neurons
◦ motor units with the longest muscle fibers
◦ motor units with larger, less excitable neurons
