Final answer:
When Michael put his hand over the hot stove, the heat was sensed by sensory neurons in his skin. These sensory neurons sent a signal to the central nervous system, specifically the spinal cord, which then initiated a reflexive withdrawal response.
Step-by-step explanation:
When Michael put his hand over the hot stove, the heat was sensed by sensory neurons in his skin. These sensory neurons sent a signal to the central nervous system, specifically the spinal cord, which then initiated a reflexive withdrawal response. This response was carried out by motor neurons that sent signals to the muscles in his arm, causing him to pull his hand away immediately.
