Let me share with you a comparison between Voluntary and Involuntary Muscles.

 

AspectVoluntary MusclesInvoluntary Muscles
Control·        These muscles are under conscious control·        Not under conscious control as these are regulated by the autonomic nervous system.
Location·        Predominantly found in skeletal muscles, attached to bones for movement.·        Found in various organs and tissues, including the heart, digestive tract and blood vessels.
Type of Muscle·        Striated and characterized by alternating dark and light bands·        Non-striated
Movement·        Responsible for intentional body movements, such as walking, running, and lifting objects.·        Control involuntary processes like digestion, heartbeat, peristalsis, and regulation of blood pressure.
Fatigue Resistance·        Can become fatigued relatively quickly, especially with strenuous exercise.·        Tend to have better endurance and are less prone to fatigue.
Contraction Speed·        Can contract rapidly and with varying degrees of force·        Typically contract more slowly and rhythmically
Nervous Control·        Controlled by the somatic nervous system, which connects to motor neurons.·        Controlled by the autonomic nervous system
