Question

Classify the following as voluntary actions and involuntary actions. Sneezing, throwing balls, heart beats, writing.

Answer 1

Voluntary actions are basically come or initiated by their own conscious actions, whereas involuntary actions are under the control of the forebrain or cerebellum of the brain.

Complete answer:
Voluntary actions:
- This actions are under the control of the once own will
- Whenever the action is required, the brain sends the impulses from it to certain parts such as muscles or glands.
- The impulses from the brain are sent to the effectors, through the spinal cord by neurons.
- Finally these impulses were sent to the motor neurons.
- Through these motor neurons, impulses are transmitted and the action required will finish.
- As above said, this action occurs through the own will of the person, hence it is said to be voluntary actions.
- From the above given question writing and throwing the ball comes under voluntary actions.

Involuntary actions:
- Involuntary actions come under the opposite of voluntary actions.
- Involuntary actions are said to be actions without their involvement or one consciousness.
- If any action occurs in response to the specific stimulus, it is said to be involuntary actions.
- In this type of actions, the actions are not in the control of the person.
- Person does not have awareness, regarding the action performed by them.
- One of the most common involuntary actions that usually displayed by all humans and mammals is heart beat, where it is not under the control of persons.
- So from the above explanation sneezing and heartbeat come under involuntary actions.

Note: Some of the other examples for involuntary actions are hiccups, coughing, digestion and breathing for some time, but breathing is not completely involuntary action, because sometimes it can be held by the person.
