Direction: Some of the action like moving our limbs , fingers, moving...

Explanation:

Involuntary actions:
- Involuntary actions are those actions that are not under our conscious control.
- These actions are controlled by the autonomic nervous system and occur automatically without us having to think about them.
- Examples of involuntary actions include blinking of eyes, heartbeat, digestion, and breathing.

Difference from voluntary actions:
- In contrast to involuntary actions, voluntary actions are under our conscious control.
- Voluntary actions are movements that we choose to make, such as moving our limbs, fingers, or turning our heads.

Significance:
- Involuntary actions are essential for the proper functioning of our body without us having to actively think about them.
- The autonomic nervous system controls involuntary actions to maintain homeostasis and ensure that our body functions properly without conscious effort.

Conclusion:
- Involuntary actions play a crucial role in maintaining the body's internal environment and allowing us to carry out daily activities without having to consciously control every bodily function.
