5 Written questions

5 Matching questions

  1. Calcium is stored in the:
  2. Central Nervous System
  3. Sympathetic Nervous System
  4. Adaptations due to weight training
  5. Repolarization
  1. a a branch of the autonomic nervous system and prepares the body for quick action in emergencies; "fight or flight"
  2. b Sarcoplasmic Reticulum
  3. c Channels for K+ open and it leaves cell
  4. d Increased ability to maintain cardiac output against increased BP during weight training
  5. e consists of the brain and spinal cord

5 Multiple choice questions

  1. • Located within the skeletal muscle
    • 2 functions: monitor stretch and length of muscle
    • initiate a contraction when muscle is stretched
  2. Transport O2 to tissues and removal of waste (CO2)
    Transport nutrients to tissues
    Regulation of body temperature
  3. can bind calcium
  4. • Located in the tendon
    • 2 functions: monitor and respond to tension in tendon
    • inhibits actin of muscle to prevent injury
  5. a higher percentage of type I fibers

5 True/False questions

  1. Contractile Propertieso maximal for production
    o Speed of contraction
    o muscle fiber efficiency

          

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

          

  3. The breakdown of ATP in muscle is accomplishment via enzyme:• 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

          

  4. As Sarco relaxesIt returns to original length
    Less overlap between actin and myosin

          

  5. The formation of cross bridges in the contractile process in skeletal muscle is initiated by:Calcium binding to tropomyosin
