Muscle cells possess myofilaments, elaborate versions of the actin and myosin filaments that bring about movement or contraction in all cell types. There are three kinds of muscle tissue: skeletal, cardiac, and smooth.  Main differences among muscular tissues Point of Skeletal Smooth muscle Cardiac muscle comparison muscle Shape Cylindrical in Spindle in Cylindrical in shape shape shape Location Found in limb Found in GIT Found in wall of ,body wall, and gland heart face and neck Striation Striated Un Striated Striated Action Voluntary in Involuntary in Involuntary in action action action Fatigue They soon get They do not get They never get  Point of Skeletal muscle Smooth muscle Cardiac muscle comparison Nucleus Nuclei are Nuclei are Nuclei are peripheral central central Nucleus Multinucleated Uninucleated Uninucleated Intercalated Intercalated Intercalated Intercalated disk disk are absent disk are absent disk are present Branching Fibers are Fibers are Fibers are unbranched unbranched branched
