5 Written questions

5 Matching questions

  1. Fasciculus
  2. ATP
  3. Skeletal muscle structure
  4. Muscular fascia
  5. Properties of muscle
  1. a contractility-shorten forcefully, excitability-response to stimuli, extensibility-stretched beyong normal resting length, elasticity-can recoil to its original resting length after being stretched
  2. b Superficial to the epimysium, separates and compartmentalizes individual muscles or groups of muscles
  3. c Bundle of muscle fibers ensheathed by perimysium
  4. d provides immediate energy for muscle contractions from 3 sources; creatine phosphate, anaerobic respiration, and aerobic respiration
  5. e Muscle fibers or cells- Develop from myoblasts, numbers remain constant, just increase in size
    Connective tissue surrounds muscle and extends beyond to become tendons to connect it to bones or dermis of skin
    Nerve and blood vessels abundant

5 Multiple choice questions

  1. muscle plasma membrane in the area of the junction
  2. small sacs that contain Acetylcholine, a neurotransmitter
  3. During resting conditions stores energy to synthesize ATP; provides enough energy to sustain max contractions for about 8-10 seconds
  4. Muscle fiber (cell) plasma membrane
  5. single motor neuron and all the muscle fibers innervated

5 True/False questions

  1. Sliding-filament modelActin myofilaments slides over myosin to shorten sarcomeres, actin and myosin do not change length
    Shortening sarcomeres is responsible for skeletal muscle contraction and during relaxation, sarcomeres lengthen

          

  2. Isotonic contractionsChange in length but tension constant. Can be concentric, overcomes opposing resistance and muscle shortens or eccentric, tension maintained but muscle lengthens

          

  3. Psychological fatiguemost common type, depends on emotional state of individual

          

  4. Complete tetanusNo relaxation between contraction

          

  5. Rigor mortisDevelopment of rigid muscles several hours after death; caused from a stop of ATP production
