Hello! dear,
Your answer goes like this ....
"This is what actually happens":-
1.Receptor detects a stimulus and then it changes the environment.
2.Sensory Nuerone sends signals to re;ay nuerone.
3.Motor nueron sneds signals to effector.
4.Effector produces a response.
Thank you dear,
Hope It helps.

A rapid automatic response to a stimulus is known as a reflex action.
1) The stimulus acts up and is recognised by the receptors. An electrical impulse gets generated.
2) This electrical impulse travels to through the sensory nerves and goes to the central nervous system.
3)The central nervous system interprets the electrical impulse and then decides the response to be given in the form of electrical impulse and is sent to the effector through the motor nerves.
4) The effector then decides it's movement according to the message given.
