10. Broad sheet of connective tissue that attaches muscles to bones indirectly or to other muscles (sheet like tendon labeled on your muscles diagram)

11. What is an aponeurosis?

12. Type of muscle with striations, multiple nuclei, attached to the skeleton, and are voluntary

13. What is skeletal muscle?

14. The contractile unit of a muscle cell, or the space between 2 Z discs

15. What is a sarcomere?

16. Neurotransmmitter that initiates muscular contraction

17. What is acetylcholine (ACh)?

18. Part of the muscle cell which stores Calcium before and after contraction

19. What is the sarcoplasmic reticulum?

20. One neuron and all the muscle cells that it stimulates

21. What is a motor unit?

22. Muscle that closes, purses and protrudes the lips in a kissing action

23. What is the orbicularis oris?

24. Muscle that is the prime mover of arm abduction

25. What is the deltoid?

26. Muscle that is the prime mover of plantarflexion

27. What is the gastrocnemius?

28. Deepest muscle of the abdominal wall named for direction of fibers

29. What is the transversus abdominis?

30. A cramp of this muscle might give you a “crick” in your neck

31. What is the sternocleidomastoid?

32. Muscle paralysis condition in which the receptors of the sarcolemma are blocked from receiving the Acetylcholine released at the synaptic cleft

33. What is myasthenia gravis?

34. General term used to describe when muscle decreases in size

35. What is atrophy?

36. A spasmodic contraction associated
A spasmodic contraction associated with pain (usually caused by fatigue or strain)

37. What is a cramp?

38. Tense/ spasmodic muscle; not relaxing (literally means muscle tension)

39. What is myotonia?

40. Term used to describe decreased muscle tone (not decreased muscle mass)

41. What is hypotonia?

42. Myofilaments that have “heads” and form cross bridges with actin, allowing them to join together

43. What are MYOSIN/ thick filaments?

44. Invaginations of the sarcoplasm through which nerve impulses travel to the sarcoplasmic reticulum

45. What are transverse tubules?

46. Name of the theory that explains muscle contraction and how the actin and myosin filaments stay the same length and overlap with each other

47. What is the Sliding Filament Theory?

48. Substance that exposes the myosin binding sites on actin filaments, allowing myosin and actin to attach

49. What is calcium?

50. Reason for the striations in skeletal muscle

51. What are myofilaments? (arrangement of thick and thin myofilaments)

52. The main function of muscle tissue

53. What is movement ? (movement produced by muscles acting with the skeletal system; muscle movement caused by muscle contraction stimulated by the nervous system)

54. Connective tissue structure that attaches muscle to bone

55. What is a tendon?

56. DAILY
DOUBLE

57. Type of contraction in which muscle filaments slide past each other and the muscle contracts, causing movement

58. What is isotonic?

59. Type of contraction in which muscles do not actually shorten, they stay the same length and there is no major movement (like in holding a stretch)

60. What is isometric?

61. State of sustained partial contraction maintains this function of the muscular system

62. What is maintaining posture?
