  1. The Muscular System Anatomy and Physiology Flash Cards Associated Bodywork & Massage Professionals

  2. Directions • The first slide asks a question. • The second slide answers the question. • Use these slides like flash cards to test your core knowledge. Associated Bodywork & Massage Professionals

  3. Question Associated Bodywork & Massage Professionals Name the three types of muscle tissue and their classifications.

  4. Answer Associated Bodywork & Massage Professionals Skeletal muscle = striated and voluntary Cardiac muscle = striated and involuntary Smooth muscle = non-striated and involuntary

  5. Question Associated Bodywork & Massage Professionals What are the dark bands in cardiac muscle tissue called?

  6. Answer Associated Bodywork & Massage Professionals Intercalated disks

  7. Question Associated Bodywork & Massage Professionals What is the origin of a muscle?

  8. Answer Associated Bodywork & Massage Professionals The muscle attachment to a stationary bone.

  9. Question Associated Bodywork & Massage Professionals The attachment to a moveable bone is called the ______.

  10. Answer Associated Bodywork & Massage Professionals Insertion

  11. Question Associated Bodywork & Massage Professionals What do tendons do?

  12. Answer Associated Bodywork & Massage Professionals Tendons connect muscle to bone.

  13. Question Associated Bodywork & Massage Professionals The microscopic structure of a muscle consists of specialized contractile cells called muscle fibers. Each muscle fiber is filled with two structures called thick and thin myofilaments. What are the names for the thick and thin myofilaments?

  14. Answer Associated Bodywork & Massage Professionals • Thick=myosin • Thin=actin

  15. Question Associated Bodywork & Massage Professionals What is a sarcomere?

  16. Answer Associated Bodywork & Massage Professionals The contractile unit of a skeletal muscle.

  17. Question Associated Bodywork & Massage Professionals Explain the sliding filament theory.

  18. Answer Associated Bodywork & Massage Professionals During contraction, the actin and myosin in a muscle fiber attach to each other by forming bridges acting as levers to pull the myofilaments past each other. Calcium must be present.

  19. Question Associated Bodywork & Massage Professionals What does adenosine triphosphate (ATP) do?

  20. Answer Associated Bodywork & Massage Professionals It provides energy for muscle cells.

  21. Question Associated Bodywork & Massage Professionals What are the functions of skeletal muscle?

  22. Answer Associated Bodywork & Massage Professionals • Movement • Posture or muscle tone • Heat Production

  23. Question Associated Bodywork & Massage Professionals In providing movement, skeletal muscle have prime movers (agonists), synergists, and antagonists. Please define.

  24. Answer Associated Bodywork & Massage Professionals Prime movers (agonists): carries out the action. Synergists: supports the prime mover. Antagonists: muscles with actions opposite of those of the prime movers.

  25. Question Associated Bodywork & Massage Professionals We can maintain an upright position during standing, sitting, etc., because of a specialized skeletal muscle contraction called ______.

  26. Answer Associated Bodywork & Massage Professionals Tonic contraction

  27. Question Associated Bodywork & Massage Professionals What is a motor unit?

  28. Answer Associated Bodywork & Massage Professionals A single motor neuron and all the skeletal muscle cells it innervates.

  29. Question Associated Bodywork & Massage Professionals The minimal level of stimulation required to cause a fiber to contract is called the ______.

  30. Answer Associated Bodywork & Massage Professionals Threshold stimulus

  31. Question Associated Bodywork & Massage Professionals What is muscle wasting?

  32. Answer Associated Bodywork & Massage Professionals Atrophy

  33. Question Associated Bodywork & Massage Professionals Looking at a cross section of a muscle belly, many cylindrical structures called fascicles can be seen. Fascicles are bundles of ______.

  34. Answer Associated Bodywork & Massage Professionals Muscle fibers

  35. Question Associated Bodywork & Massage Professionals Once stimulated by a threshold stimulus, a muscle fiber will contract completely. This response is called ______.

  36. Answer Associated Bodywork & Massage Professionals All or none
