Q. Consider the following types of actions:

1. Reflex action
2. Voluntary action
3. Involuntary action

Which of the above are responses mediated by the nervous system?
Answer: All of the above
Notes: Reflex, voluntary, and involuntary actions are all responses mediated by the nervous system. Reflex actions are rapid, automatic responses to stimuli via reflex arcs. Voluntary actions involve conscious control, whereas involuntary actions occur without conscious intent. Each type utilizes components of the nervous system for initiation or coordination of response.
