Juan picks up a steel utensil and immediately drops it because it’s extremely hot. How does the reflex arc work to protect Juan from a worse burn?

Three main types of neuron: sensory, motor and relay they 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.

Explanation:

In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain and protect Juan from worse burns.
