Reflex action is a type of?
Correct answer: B. Involuntary action
- A. Voluntary action
- B. Involuntary action
- C. Saltatory conduction
- D. None of these options is correct
Explanation
A reflex action is an automatic (involuntary) and rapid response to a stimulus, which minimizes any damage to the body from potentially harmful conditions, such as touching something hot. Reflex actions are therefore essential to the survival of many organisms. A reflex occurs via neural pathways in the nervous system called reflex arcs. Since all the reflex actions are involuntary (i.e, we can not control them according to our will), option B is right.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
