Which of the following actions is not an example of a simple reflex action?
Answer Details
Reading a book is not an example of a simple reflex action.
Simple reflex actions are automatic, involuntary and rapid responses of the body to a stimulus. They involve sensory neurons that detect the stimulus, and motor neurons that produce a quick response without involving the brain.
Knee jerk, blinking of the eye, withdrawal of hand from hot object, and contraction of the iris are all examples of simple reflex actions. However, reading a book is a voluntary action that involves higher brain functions such as perception, comprehension, and memory. It is not a reflex action.
