Final answer:

Reflex arcs swiftly protect individuals from harm by triggering rapid muscle responses to dangerous stimuli.


Explanation:

Reflex arcs play a vital role in protecting individuals from harm in potentially dangerous situations. For example, when Juan touches the hot steel utensil, the sensory receptor in his hand detects the heat and sends a nerve impulse via a sensory nerve to the spinal cord. The impulse then passes to an interneuron and finally to a motor nerve, triggering a rapid muscle contraction that causes him to drop the hot utensil.
