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 protective response is known as {reflex action}. This is an automatic, unconscious reaction to a trigger. For instance, when touching something hot, sensory neurons sense the heat and transmit signals to the spinal cord. The spinal cord swiftly signals muscles to move the hand away, all without conscious control.
