A. a higher B. a lower C. the same (Question 2) In a lab, wave summation is demonstrated by increasing the _________ of the stimulus. A. intensity B. frequency C. capacitance D. warm up time (Question 3) Which contraction occurs when you try (unsuccessfully) to move a wall? A. Isometric B. Isotonic (Question 4) . During REM sleep, muscle tone decreases significantly. Indicate whether this statement is true or false. (Question 5) A continuous, smooth contraction of muscle in which twitches are fully fused is referred to as _________. Fill in the blank with correct word. (Question 6) Staircase and warming-up effect refer to ___________, an increased muscle response to a constant stimulus. A. wave summation B. treppe C. multiple motor unit summation D. incomplete tetany E. isotony (Question 7) Muscle tone is a result of _________ nervous system activity, and it acts to _________ joint position. A. involuntary, stabilize B. involuntary, continuously vary C. voluntary, stabilize D. voluntary, continuously vary (Question 8) In a graph of wave summation, the tension level returns to baseline between each peak of force. Indicate whether this statement is true or false. (Question 9) Consider the difference between lifting a light pad of paper versus a heavy textbook. The primary way the level of force of muscle contraction is controlled is by A. recruiting a different number of motor units. B. activating different regions of the muscle. C. activating the motor units at a different frequency. D. altering the number of crossbridges each individual fiber uses. (Question 10) A graph of a muscle twitch contains three periods. The period during which there is no change in external muscle tension (and no change in muscle length) is the ________ period. Fill in the blank with correct word.
