Reflex action is an immediate response to a specific stimulus without conscious control. Spinal reflexes are controlled by the spinal cord. And the spinal cord and the brain are Reflex centres.Examples of reflex actions are scratching when your skin is itchy, the sudden blinking of the eye when a hand is waved in front of it, and also salivation when food is in the mouth.
A stimulus is not a reaction, a stimulus is what causes a reaction.
The reaction to a stimulus is called a response. An intensified stimulus usually evokes a more intense response. Of course the type of response to a stimulus depends on the nature of the stimulus. Scream at someone and they likely will feel verbally attacked. The screaming is the stimulus, feeling attacked is the response.
Reaction time is the time it takes from a stimulus being received to react to that stimulus. For example, If you step on a bee barefooted (sting of the bee is the stimulus), your reaction time is the time it takes to remove your foot.

An automatic response to an environment is known as a reflex. This is a quick, involuntary reaction to a stimulus that helps protect the body from harm. Reflexes are controlled by the spinal cord and do not require conscious thought.
