Detailed explanation-1: -Reflex is an involuntary and sudden response to stimuli.
Detailed explanation-2: -A reflex action is an automatic (involuntary) and rapid response to a stimulus, which minimises any damage to the body from potentially harmful conditions, such as touching something hot.
Detailed explanation-3: -Reflex actions happen through the reflex arc, which is a neural pathway that controls the reflexes. The receptor here is the sense organ that senses danger. The sensory neurons pick up signals from the sensory organ and send them through other neurons which are interconnected.
Detailed explanation-4: -If the spinal cord was not in charge of the reflex action, the actions would inevitably be under the control of the brain which would make the transmission and receiving time much more.
