Major functions of muscle
•
•
•
•
Regulating movement
Stabilizing body positions
Movement of materials around body
Properties:
Excitability
Contractility
Extensibility
Elasticity
3 different types of muscle
• Skeletal
– Move skeleton
– Striated
– Voluntary
• Cardiac
– Striated
– Involuntary
– Autorhythmicity
• Smooth
– Not striated
– Usually involuntary
– Some
autorhythmicity
