RELEX ACTION

 Reflex is an involuntary and sudden response to stimuli.
 It happens to be an integral component of the famed survival instinct.
 Most of the common reflexes are a response to all the well trained, accumulated knowledge
of caution that we have internalized.
 It could be anything and ranges from the reflex action of abruptly withdrawing the hand as it
comes in contact with an extremely cold or hot object.
 This action is termed as the reflex action.
 It has a subtle relation to instinct.
 They are not controlled by our brain but our spinal cord.
 When the sensory nerves detect the object touched is very hot or cold, they immediately
send message to the spinal cord.
 The spinal cord then sends back the message to the hand through the motor nerves to
withdraw the hand.
 Reflex actions are so fast that occurs almost in a fraction of seconds.
