1. Skeletal Muscle • Muscle that is attached to bones • Contraction forces movement of the body • Voluntary control • Striated fibers
2. Cardiac Muscle • Found only in the heart • Contraction forces the heart to beat • Involuntary control • Striated, branched fibers • Intercalated discs
3. Smooth Muscle • Found in the walls of hollow internal organs • Contraction forces the movement of substances through a tube (blood vessels, GI tract, urinary tract, etc.) • Involuntary control • No striations
Communication- detect stimuli • Coordination – integrate information • Control – transmit signals • Composed of 2 cell types: • Neurons – transmit messages • Neuroglia – provide supportive functions to the neurons Function Characteristics
