    SMOOTH MUSCLE

    Characteristics:
    involuntary, non-striated, single nucleus; may possess gap junctions.

    Function: constriction and dilatation (involuntary movement).

    Location: lines blood vessels, GI tract, respiratory tract, organs, reproductive structures, attached to hair follicles, and in the iris and cilliary body of the eye, etc.

    CARDIAC MUSCLE

    Characteristics:
    involuntary, striated, intercalated discs, single nucleus, muscle fibers anastomose.

    Function: create pumping action require to distribute blood throughout the body through contraction.

    Location: myocardium of heart.
  3. Image Upload
    SKELETAL MUSCLE

    Characteristics:
    voluntary, striated, multi-nucleated; muscles are surrounded by epimysium, fascicles by perimysium, and muscle fibers by endomysium; A&I bands visible.

    Function: voluntary movement of body.

    Location: attached to bone (the visible muscles); ex: biceps, gastrocnemius, quadriceps, gluteus maximus, etc.
  4. Image Upload
    NEUROMUSCULAR JUNCTION (MOTOR END PLATE)

    Characteristics:
    large motor units control movement of large skeletal muscles and smaller motor units control movement of muscles of the eye; terminal bulbs do not actually make physical contact with muscle fibers.

    Function: conduct action potential from motor neuron to muscle fiber; the stimulation of muscle fibers.

    Location: the muscle-nerve interface.
