31. graded muscle response modification of contraction strength
32. hyperplasia process in which one cell splits to produce new cells
33. hypertonia abnormally high muscle tone
34. hypertrophy addition of structural proteins to muscle fibers
35. hypotonia abnormally low muscle tone caused by the absence of low-level contractions
36. intercalated disc part of the sarcolemma that connects cardiac tissue, and contains gap junctions and desmosomes
37. isometric contraction muscle contraction that occurs with no change in muscle length
38. isotonic contraction muscle contraction that involves changes in muscle length
39. lactic acid product of anaerobic glycolysis
40. latch-bridges subset of a cross-bridge in which actin and myosin remain locked together
41. latent period the time when a twitch does not produce contraction
42. motor end-plate sarcolemma of muscle fiber at the neuromuscular junction, with receptors for the neurotransmitter acetylcholine
43. motor unit motor neuron and the group of muscle fibers it innervates
44. muscle tension force generated by the contraction of the muscle; tension generated during isotonic contractions and isometric contractions
45. muscle tone low levels of muscle contraction that occur when a muscle is not producing movement
46. myoblast muscle-forming stem cell
47. myofibril long, cylindrical organelle that runs parallel within the muscle fiber and contains the sarcomeres
48. myogram instrument used to measure twitch tension
49. myosin protein that makes up most of the thick cylindrical myofilament within a sarcomere muscle fiber
50. myotube fusion of many myoblast cells
51. neuromuscular junction (NMJ) synapse between the axon terminal of a motor neuron and the section of the membrane of a muscle fiber with receptors for the acetylcholine released by the terminal
52. neurotransmitter signaling chemical released by nerve terminals that bind to and activate receptors on target cells
53. oxygen debt amount of oxygen needed to compensate for ATP produced without oxygen during muscle contraction
54. pacesetter cell cell that triggers action potentials in smooth muscle
55. pericyte stem cell that regenerates smooth muscle cells
56. perimysium connective tissue that bundles skeletal muscle fibers into fascicles within a skeletal muscle
57. power stroke action of myosin pulling actin inward (toward the M line)
58. pyruvic acid product of glycolysis that can be used in aerobic respiration or converted to lactic acid
59. recruitment increase in the number of motor units involved in contraction
60. relaxation phase period after twitch contraction when tension decreases
