  Function of Muscles
  •Produce movement
  •Maintain posture
  •Stabilize joints
  •Generate heat
    The Muscular System
    • Muscles are responsible for all types of body movement
    • Three basic muscle types are found in the body
     • Skeletal muscle
     • Cardiac muscle
     • Smooth muscle
   Characteristics of Muscles
   • Muscle cells are elongated 
   (muscle cell = muscle fiber)
   • Contraction of muscles is due to the movement of 
   microfilaments
   • All muscles share some terminology
    • Prefix myo refers to muscle
    • Prefix mys refers to muscle
    • Prefix sarco refers to flesh
    Skeletal Muscle Characteristics
    • Most are attached by tendons to bones
    • Cells are multinucleate
    • Striated – have visible banding
    • Voluntary – subject to conscious control
    • Cells are surrounded and bundled by connective tissue
             Connective Tissue Wrappings of 
             Skeletal Muscle
                • Endomysium – around 
                  single muscle fiber
                • Perimysium – around a 
                  fascicle (bundle) of fibers
                                                                       Figure 6.1
