Questions and Answers

What type of muscle contraction involves muscle tension developing at constant muscle length?

  • Isotonic muscle contraction
  • Auxotonic muscle contraction
  • Eccentric muscle contraction
  • Isometric muscle contraction (correct)

    • What is the primary characteristic of isotonic muscle contraction?

  • Muscle contraction without movement
  • Muscle tension developing at constant muscle length
  • The load remains constant as the muscle changes length (correct)
  • Continuous partial contractions of skeletal muscle

    • What is the function of tendon in muscle contraction?

  • Stimulating various fibers under involuntary control
  • Causing continuous partial contractions of skeletal muscle
  • Shortening muscles and moving bones
  • Transmitting tension generated by contractile elements to the bone (correct)
