Question

What is the difference between voluntary movement and involuntary movement?

1) Voluntary movement is consciously controlled by the organism, while involuntary movement occurs naturally.
2) Voluntary movement occurs naturally, while involuntary movement is consciously controlled by the organism.
3) Voluntary movement and involuntary movement are the same.
4) Voluntary movement and involuntary movement are both controlled by external factors.

Answer 1

Voluntary movements are those under conscious control, like using skeletal muscles to walk, whereas involuntary movements happen without conscious thought, such as the beating of the heart by cardiac muscles. The autonomic nervous system governs involuntary muscle actions. Therefore, the correct answer to the question is: 1) Voluntary movement is consciously controlled by the organism, while involuntary movement occurs naturally.

Step-by-step explanation:

Difference Between Voluntary and Involuntary Movements

The main difference between voluntary movement and involuntary movement lies in the control we have over these actions. Voluntary movements are those that are consciously controlled by an individual's will, such as the movement of your legs when you decide to walk.

For instance, the skeletal muscles that move your limbs are under voluntary control. On the other hand, involuntary movements occur without the need for conscious thought and are not under our conscious control.

Examples of involuntary muscles include the cardiac muscles of the heart and the smooth muscles found within the walls of internal organs like the stomach and intestines which function without conscious effort. These involuntary actions are controlled by the autonomic nervous system.

Therefore, the correct answer to the question is: 1) Voluntary movement is consciously controlled by the organism, while involuntary movement occurs naturally.
