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: -In a two-neuron arc, simple reflexes are prompt, short-lived, and automatic and involve only a part of the body. Examples of simple reflexes are the contraction of a muscle in response to stretching, the blink of the eye when the cornea is touched, and salivation at the sight of food.
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.
Detailed explanation-4: -These different types of neurons work together in a reflex action . A reflex action is an automatic (involuntary) and rapid response to a stimulus, which minimises any damage to the body from potentially harmful conditions, such as touching something hot.
