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

 

Aspect Voluntary Muscles Involuntary 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
Examples

 

·        Skeletal muscles

 

·        Smooth muscle in the digestive tract, blood vessels and other internal organs.
