SELECT ALL CORRECT ANSWERS 16) What characteristics would increase a given muscle's range of motion? A) An increased number of sarcomeres in series B) A multipennate arrangement of the muscle fibers C) Increased sensitivity of the muscle spindle fiber D) More heavily myelinated axons on the motor neurons E) Greater acetylcholine release at the neuromuscular junction 17) Force from a single fiber's contraction will be higher as a result of all of the following EXCEPT A) recruitment of more of the motor neuron pool B) generation of ipsp's C) release of more acetylcholine for a bigger action potential D) number of sarcomeres in the muscle E) a decrease in the amount of calcium released from the SR 18) Force from a whole muscle's contraction will be higher as a result of all of the following EXCEPT A) recruitment of multiple motor units B) stimulation of all 3 types of muscle fibers C) a reduction in GTO activity D) synchronous neural stimulation E) a reduction in muscle spindle activity.
19) Action potentials rely on A) voltage-gated channels for depolarization and repolarization B) calcium in muscle cells C) myelination of the membrane to speed up their propagation D) changes in sodium-potassium pump activity E) processes like spatial summation and cancellation to allow for coordinated responses 20) Which of the following does NOT bind to troponin A) actin -B) calcium C) myosin. D) titin E) tropomyosin
21) Packing of thin and thick filaments A) is in a hexagonal packing pattern B) results in more thick than thin filaments C) is arranged to maximize the number of crossbridges per unit cross-sectiul area D) uses nebulin as a scaffold for building thin filaments E) requires M protein for the building of the thick filament 22) Which of the following is TRUE? A) While individual regions shorten during contraction, the si comere as a whole does not B) Calcium serves to regulate the contractile activity of muscle fibers C) Due to their all-or-none nature, action potentials in the muscle will result in the same speed of contraction even in different muscle fiber types D) The higher the nerve to muscle ratio, the more force production there will be E) T-tubules run parallel to the sarcomeres myofilaments 23) Muscle fiber type ratios A) tend to differ person-to-person B) tend to differ muscle-to-muscle C) are largely dependent on sex D) display higher type Il a fibers in athletes than non-athletes E) are highly trainable, i.e., not highly genetically determined 24) Which of the following is true about eccentric training A) Eccentric training is more productive than regular lifting in leading to gains in muscle mass B) Maximum force generation is higher during eccentric than concentric contractions C) Eccentric lifting is safer than concentric training D) Eccentric lifting is more likely to lead to DOMS E) Eccentric lifting is particularly good at strengthening type I muscle fibers
