  1. Ch 6 Not-so-clicker Review Muscular System Write your answers on paper. You will get correct answers at the end. There are 60 multiple choice, T/F, matching questions and one paragraph prompt response.

  2. 1. Muscle that aides another by promoting the same movement • Prime mover • Antagonist • Synergist • Fixator

  3. 2. Stores neurotransmitters • Motor unit • Motor end plate • Motor nerve ending • Synaptic cleft

  4. 3. Mechanical force of contraction is generated by • Shortening of actin • Shortening of myosin • Sliding of actin over myosin • Sliding of myosin over actic

  5. 4. Stores Ca+ ions • Sarcolemma • Sarcoplasmic reticulum • Sarcomere • Motor end plates

  6. 5. An example of isometic contraction • Jogging • Leaning • Writing • Drinking

  7. 6. A twitch is • Brief and normal • Brief and abnormal • Long and normal • Long and abnormal

  8. 7. Stabilizes the origin of another muscle • Prime mover • Antagonist • Synergist • Fixator

  9. 8. Stores energy that can directly transfer to ADP to make ATP • Glucose • Lactic acid • Creatine phosphate • Sacroplasmic reticulum

  10. 9. Contains only actin • A band • I band • Z line • H zone

  11. 10. Movement away from midline • Pronation • Adduction • Abduction • Extension

  12. 11. The actual “go” signal for muscle contraction • Calcium ions • Potassium ions • Sodium ions • ACh

  13. 12. Nerve cell and the muscle cells that it stimulates • Motor unit • Motor end plate • Fascicle • Axonal terminal

  14. 13. Both actin & myosin found here • A band • I band • Z line • H zone

  15. 14. When flexing forearm at elbow • Biceps is antagonist • Triceps is synergist • Triceps is antagonist • Deltoid is antagonist

  16. 15. Cause of muscle fatigue • Lack of oxygen • Build up of lactic acid • Too much creatine • Aerobic respiration

  17. 16. Sustained partial contraction • Isotonic • Isometric • Tone • Fused tetanus • Unfused tetanus

  18. 17. Neurotransmitter released from end of neuron • Acetylcholine • Sodium ions • Calcium ions • Sarcoplasmic reticulum

  19. 18. Not function of muscular system • Generate heat • Movement • Stabilize joints • Hematopoiesis • Maintain posture

  20. 19. Opposes and reverses action of another muscle • Prime mover • Antagonist • Synergist • Fixator

  21. 20. Connective tissue around one muscle fiber (cell) • Fascia • Endomysium • Perimysium • Epimysium

  22. 21. Put in order from smallest to largest 1. Fiber cell 2. Myofilament 3. Myofibril 4. Fascicle • 1, 2, 3, 4 • 4, 3, 2. 1 • 2, 3, 1, 4 • 4, 1, 3, 2

  23. 22. Destroys ACh • K+ ions • Na + ions • Ca+ ions • Enzymes

  24. 23. Distance between two Z lines • Sarcoplasmic reticulum • Sarcolemma • Sarcoplasma • Sarcomere

  25. 24. Sheet-like connective tissue • Tendon • Aponeurosis • Sarcolemma • Myofiber

  26. 25. Insertion of biceps brachii • Ulna • Scapula • Radius • Clavicle • Humerus

  27. 26. Which term doesn’t belong? • Striated • Multinucleic • Involuntary • Cylindrical

  28. 27. Provides the most ATP per Glucose • Glycolysis • Anaerobic respiration • Aerobic respiration • Direct phosphorylation

  29. 28. Striations are caused by overlapping • Dark and light bands • I and A bands • Myosin and actin • Arrangement of myofilaments • All of the above

  30. 29. Thick filaments • Actin • Myosin • Sarcomere • Myofibrils

  31. 30. Function of Ca+ ions • Change sarcolemma’s permeability • Expose myosin binding sites • Pump Na+ ions out of cell • Break down left over ACh

  32. 31. Function of neurotransmitter • Release Ca+ ions • Change membrane permeability • Release K+ ions • Maintain tone

  33. 32. Flexes the knee • Quads • Hamstrings • Gastrocnemius • Gluteus medius

  34. 33. Cannot be seen during contraction • Z lines • Dark bands • H zone and I bands • Cross bridges

  35. 34. Involuntary • Cardiac only • Smooth and cardiac • Skeletal and cardiac • Smooth and skeletal

  36. 35. Made of Actin • Dark bands • Light bands • Thick bands • Thin bands • A and C above • B and D above

  37. 36. “All or None” means the ___ will contract only its entire length. • Muscle • Fascicle • Fiber

  38. 37. Name the 4 connective tissues

  39. Know muscle movement pictures for • Abduction • Adduction • Rotation • Flexion • Extension • Circumduction • Pronation • Supination • Dorsiflexion • Plantar flexion

  40. Check your answers: 37. Connective tissues from top to bottom endomysium perimysium epimysium tendon
