5 Written questions

5 Matching questions

  1. As Sarco Shortens
  2. Mitochondria
  3. Atrioventricular node
  4. force velocity curve
  5. Muscle Spindles
  1. a ability of muscles to produce force w/ increasing velocity. muscle force increases, velocity of contraction decreases
  2. b • Located within the skeletal muscle
    • 2 functions: monitor stretch and length of muscle
    • initiate a contraction when muscle is stretched
  3. c actin filaments slide over myosin.
    Z-lines approach end of myosin filaments
  4. d delays impulse by 1/10 of second, allowing atria to contract before ventricles
  5. e ATP production through aerobic metabolism

5 Multiple choice questions

  1. the junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron
  2. rapidly spreads impulse to contract throughout ventricles
  3. channels for Na+ open and enters cell
  4. • Ability to repeat a specific motor unit recruitment pattern
    • Results in success performance of a skill
    • Requires practice
  5. long nerve fiber that conducts away from the cell body of the neuron

5 True/False questions

  1. Type IIa Fibers• Intermediate Fibers
    • Fast-oxidative
    • Glycolic fibers
    • Anaerobic and Aerobic

          

  2. Isotonico Muscle exerts force without changing length
    o Pulling against immovable actions
    o Postural muscles

          

  3. The motor neuron and all the muscle fibers it innervates are called a motor:neuromuscular junction

          

  4. Adaptations due to weight trainingIncreased ability to maintain cardiac output against increased BP during weight training

          

  5. RepolarizationInitiates contraction of muscles and limb movements
