ii.. heartbeat, digestion of food, peristaltic movement, etc; came under involuntary actionable.

Thank you.. :-)

Answer

Involuntary actions:-
- They involve autonomic nervous system .
- They involve functioning of the internal body parts.
- The nervous system controlling involuntary actions has two divisions , sympathetic n parasympathetic .
- They occur in response to internal stimuli.
- Most of the involuntary functions occur all the time.
- They are Carried out by smooth muscles.
Reflex actions :-
-They involve all parts of voluntary nervous system though they are not under our control.
- They are concerned with emergency.
-They have no divisions.
- They commonly operate against harmful stimuli , which are generally external.
- Reflex actions occur occasionally.
-They are performed by striated muscles.

Answer

Reflex Action vs Involuntary Actions

Reflex action and involuntary actions are two types of automatic responses that happen in the human body. While these two types of responses may seem similar, they are actually quite different in terms of their cause and control.

Reflex Action

Reflex actions are the automatic responses that happen in the body without conscious thought or decision-making. These actions are triggered by a specific stimulus and are designed to protect the body from harm or injury. Examples of reflex actions include:

- Blinking when something comes close to the eyes
- Withdrawing a hand from a hot stove
- Sneezing when something irritates the nose

Reflex actions are controlled by the spinal cord and brainstem, which are responsible for processing sensory information and triggering a motor response. These actions are fast, automatic, and do not require any conscious thought or decision-making.

Involuntary Actions

Involuntary actions, on the other hand, are automatic responses that happen in the body without conscious control, but they are not necessarily triggered by a specific stimulus. These actions are regulated by the autonomic nervous system, which controls the functions of the body that are not under conscious control. Examples of involuntary actions include:

- Breathing
- Heartbeat
- Digestion

Unlike reflex actions, involuntary actions are not triggered by a specific stimulus and are not designed to protect the body from harm or injury. These actions are ongoing processes that happen automatically and are regulated by the autonomic nervous system.

Differences Between Reflex Action and Involuntary Actions

The main differences between reflex action and involuntary actions are:

- Reflex actions are triggered by a specific stimulus, while involuntary actions are ongoing processes that happen automatically.
- Reflex actions are designed to protect the body from harm or injury, while involuntary actions are not necessarily related to protection.
- Reflex actions are controlled by the spinal cord and brainstem, while involuntary actions are regulated by the autonomic nervous system.

Conclusion

In summary, while both reflex action and involuntary actions are automatic responses that happen in the body without conscious control, they are quite different in terms of their cause and control. Reflex actions are triggered by a specific stimulus and are designed to protect the body from harm or injury, while involuntary actions are ongoing processes that happen automatically and are regulated by the autonomic nervous system.
