Significance of reflex action :
1. Reflex action helps the animals to adjust quickly to the changing environment.
2. Reflex action is for quick actions necessary for survival. The life may have been in danger in the absence of reflex action.
3. Most of the reflexes are spinal reflexes, i.e. reflexes controlled by spinal cord. Thus the brain is not involved in these actions. This prevents overloading of the brain and brain fatigue.
4. Some reflexes are inborn and hence training or learning is not required for these.
