2. Major functions of muscle Regulating movement Stabilizing body positions Movement of materials around body Properties:  Excitability  Contractility  Extensibility  Elasticity Regulating movement Stabilizing body positions Movement of materials around body Properties:  Excitability  Contractility  Extensibility  Elasticity

3. 3 different types of muscle Skeletal – Move skeleton – Striated – Voluntary Cardiac – Striated – Involuntary – Autorhythmicity Smooth – Not striated – Usually involuntary – Some autorhythmicity Skeletal – Move skeleton – Striated – Voluntary Cardiac – Striated – Involuntary – Autorhythmicity Smooth – Not striated – Usually involuntary – Some autorhythmicity
