ANATOMY

Detailed explanation-1: -This quick response is called a reflex, and reflexes occur without conscious thinking or planning, meaning the brain is not involved in them.

Detailed explanation-2: -Reflex actions do not require the brain to think about responses before acting. Once again, the fact that reflex actions do not require conscious thought is part of the reason that they can occur so rapidly. This is an advantage of having reflex actions. Reflex actions allow a quick response to danger.

Detailed explanation-3: -Reflexes are faster than conscious thought because they involve fewer pathways of travel and information from a reflex does not need to travel to the brain. Instead, a reflex arc occurs at the level of the spinal cord which makes travel time faster than when the brain is involved in the decision making.

Detailed explanation-4: -In a reflex action, the brain plays no part. The spinal cord, which reacts without thinking about how to respond to stimuli, is in charge of these automatic actions. It elicits no meaningful response in the brain.

Detailed explanation-5: -Reflexes are involuntary actions your body takes in response to certain stimuli. That means they’re automatic. Reflexes occur without your having to think about it. Reflexes are simply natural reactions we’re all born with.
