Detailed Solution

The purpose of the reflex arc is to provide a rapid response to a stimulus without involving conscious thought.

A reflex arc is a neural pathway that mediates a reflex action. It allows for the rapid and automatic response to certain stimuli, without the need for conscious thought or decision-making. For example, when you touch a hot stove, the reflex arc causes your hand to quickly and automatically withdraw from the heat before you even have a chance to consciously process the sensation of pain.
