How does a reflex arc work?

the relfex action consists of receptor and neurons communicating together. the brain is not involved the processing of this action. The basic pathway that the reflex arc follows is: stimulus (touching something hot) → receptor (thermoreceptors)→ sensory neurone → relay neurone → motor neurone → effector (muscle) → response (lifting your hand)
