5 Written questions

5 Matching questions

  1. Sinoatrial node
  2. Proprioception & Kinetic sense
  3. The two Principal contractile proteins found in the skeletal muscle are:
  4. force velocity curve
  5. Axon
  1. a long nerve fiber that conducts away from the cell body of the neuron
  2. b ability of muscles to produce force w/ increasing velocity. muscle force increases, velocity of contraction decreases
  3. c the heart's pacemaker, located in the wall of the right atrium
  4. d • How the body sense where it is in space
    • Receptors: Located in the muscles and tendons
    • Info from proprioceptors is sent to the brain
  5. e Actin and Myosin

5 Multiple choice questions

  1. a higher percentage of type I fibers
  2. • Formation of cross bridges between actin and myosin filaments.
    • Reduction in distance between z-lines or sarcomere "power stroke"
    • ATP is required for muscle contraction
    o Myosin ATPase breaks down ATP as fiber
  3. the junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron
  4. ATP production through aerobic metabolism
  5. Basic skeletal muscle unit. Capable of force production and shortening. Arrangement of protein filaments and gives straight appearance.

  2. Learning EffectQ = HR (bmp) × SV (mL) (5-Men) (4.5-Women)

          

  3. Parasympathetic Nervous Systema branch of the autonomic nervous system and prepares the body for quick action in emergencies; "fight or flight"

          

  4. Eccentrico Muscle shortens during force production

          

  5. DepolarizationChannels for K+ open and it leaves cell
