Question
What is reflex action? Give an example of reflex action.
Answer
Reflex action is an involuntary and automatic response to a stimulus that occurs without conscious thought, involving a simple neural pathway called a reflex arc.
An example of reflex action is the knee-jerk reflex, where tapping the patellar tendon below the kneecap causes the leg to extend involuntarily, without the person consciously directing the movement.
