a reflex action is defined as a sudden involuntary response of effectors ( muscles and glands) to stimulus. in reflex action, a message from receptors is relayed by the sensory nerves to the spinal cord, which sends information for response via motor nerves to effectors. THE PATH WAY IS CALLED "REFLEX ARC"
example : the simplest kind of reflex action is knee - jerk...
in this case, while sitting with freely hanging legs, a strike below the knee cap kicks the leg forward. other reflexes are sneezing, coughing, blinking of eyes, yawning etc...
all the best!!! i hope this helped

A reflex arc is the neural pathway that mediates a reflex action. In higher animals, these pathways do not pass through the brain, but synapse in the spinal cord.
