Voluntary muscles are those you consciously control, like your biceps when raising your arm. Involuntary muscles, on the other hand, operate automatically without conscious thought, such as the heart muscle that pumps blood.
Here’s a more detailed comparison:
Voluntary Muscles:
Control: Consciously controlled by the nervous system.
Examples: Biceps, quadriceps, muscles in your arms and legs that allow you to walk, talk, and write.
Location: Attached to bones and skeletal system.
Involuntary Muscles:
Control: Operate automatically, controlled by the autonomic nervous system.
Examples: Heart muscle (cardiac muscle), smooth muscle lining the digestive tract (peristalsis), and the diaphragm.
Location: Found in internal organs and blood vessels.
