Question

What is reflex action? Explain it with an example.

Answer

A reflex action is an involuntary response to a stimulus. It is a quick, automatic response that does not require conscious thought. An example of a reflex action is the knee-jerk reflex. When the doctor taps your knee with a rubber hammer, your leg kicks out involuntarily. This is because the tap on your knee sends a signal to your spinal cord, which then sends a signal to your leg muscles to contract.

Reflex actions are important for our survival. They allow us to react quickly to danger or to other unexpected stimuli. For example, if you touch a hot stove, you will automatically pull your hand away. This reflex action helps to protect you from being burned.
