Question

In life, there are certain changes in the environment called ‘stimuli’ to which we respond appropriately. Touching a flame suddenly is a dangerous situation for us. One way is to think consciously about the possibility of burning and then moving the hand. But our body has been designed in such a way that we save ourself from such situations immediately.
Name the action by which we protect ourselves in the situation mentioned above and define it.

Hint:

Reflex actions are fast and involuntary responses to stimuli, designed for immediate protection.

Answer 1

The action by which we protect ourselves is called {reflex action}. Reflex action is an automatic and involuntary response to a stimulus. In the case of touching a hot object, the sensory neurons detect the heat and send signals to the spinal cord, which quickly sends a signal to the muscles to withdraw the hand, all without the need for conscious thought.
