Without an automatic response to a simple stimulus which does not require mental processing, a human being would not be able to react to its' own functions being harmed in any way. Example: Skin contact with fire, without a response to the flame, your skin would burn.
The reflex reaction is important as it allows for quick, automatic responses to potential threats or dangers without the need for conscious thought. This can help prevent injury or harm in situations that require immediate action.
The instinctive reaction is important because it takes time for signals to travel all the way to the brain and elicit a response - sending a message up the spinal cord takes time. Reflexes cause the body to automatically respond without waiting.

When you pet your cat and her back twitches, it is likely due to a reflex called the "scratch reflex." This reflex is a natural response in cats that causes their muscles to twitch when they are touched in certain areas, such as along their spine. It is a normal and common reaction in cats and is not usually a cause for concern.
