NPB101 LATE ST EXAM WITH 64 QUESTIONS AND 100% CORRECT ANSWERS. GRADED A+ / NPB101 EXAM 1. Treppe is the phenomenon that results in _______. A. maximal force production by a skeletal muscle B. an increase in the stimulation frequency C. a progressive increase in the force generated with repetitive stimulation D. motor unit recruitment CORRECT ANSWER IS ->> C. a progressive increase in the force generated with repetitive stimulation 2. When the frequency of stimulation of a muscle is great enough, _______. A. full relaxation of the muscle occurs B. muscle twitches overlap C. full relaxation of the muscle occurs and wave summation results D. wave summation results E. wave summation results and muscle twitches overlap. CORRECT ANSWER IS ->> E. wave summation results and muscle twitches overlap. 3. When wave summation occurs, _______. A. the muscle force generated increases B. the muscle force generated decreases C. individual muscle twitches are separated D. the muscle fiber has received a single stimulus event CORRECT ANSWER IS ->> A. the muscle force generated increases 4. Why does wave summation occur? A. Muscle fibers are partially contracted when the next stimulus arrives. B. Muscle fibers have been allowed to fully relax. C. Muscle twitches are not yet overlapping. D. A large amount of time elapses between stimulations. CORRECT ANSWER IS ->> A. Muscle fibers are partially contracted when the next stimulus arrives. 5. What is treppe? CORRECT ANSWER IS ->> progressive increase in force generated when a muscle is stimulated in succession, such that muscle twitches follow one another closely, with each successive twitch peaking slightly higher than the one before. (stair case increase) 6. During a single twitch of a skeletal muscle A. calcium is not released from the sarcoplasmic reticulum B. maximal force is never achieved C. no force produced unless the muscle shortens D. maximal force is always achieved CORRECT ANSWER IS ->> maximal force is never achieved 7. When a skeletal muscle is repetitively stimulated, twitches can overlap each other and result in a stronger muscle contraction than a stand -alone twitch. This phenomenon is known as: A. skeletal muscle tone (tonus) B. the latent period C. wave summation D. fatigue CORRECT ANSWER IS ->> C. wave summation 8. Wave summation is achieved by CORRECT ANSWER IS ->> increasing stimulus frequency (the rate of stimulus delivery to the muscle). 9. wave summation increases the force produced in the muscle. Another way to increase the force produced by a muscle is to a. slow action potential propagation down to the motor neurons that innervate the muscles b. block calcium release from the SR c. decrease the number of activated motor units d. increase the number of activated motor units CORRECT ANSWER IS ->> d. increase the number of activated motor units 10. which of the following is not one of the ways that the body can increase the force produced by a skeletal muscle? A. recruitment of more motor units and thus activation of more muscle fibers B. application of high -frequency stimulation by a motor neuron C. maintenance of elevated intracellular calcium levels, has inducing wave summation D. application of higher voltages to the whole muscle CORRECT ANSWER IS->> D.application of higher voltages to the whole muscle
