उत्तर
Voluntary action: When an action is produced with the involvement of thoughts, they are called voluntary action. For example, writing an article jumping from heights. These actions are produced consciously by our bodies.
Involuntary action: Actions that take place without consciousness or willingness of an individual are called the involuntary action. Digestion, heart beating, sneezing, etc are few examples of involuntary actions.
- The cerebral cortex controls our voluntary actions like running and walking etc.
- Medulla helps in involuntary actions like a heartbeat, breathing, etc.
