Once he landed, he landed on something squishy and bouncy. So he looks up to the lamp and asks: "What just braced my fall?"
"You landed on the Central Nervous System! It's apart of the nervous system consisting of the brain and spinal cord. It connects to the peripheral nervous system."
Jason started walking and the setting got different. He rubbed the lamp and asked: "Where am I?" The lamp responded and told Jason he was now in the Axon Terminal right by the Axon.
Then the lamp says: "Look! There's a myelin covering that nerve." So Jason started using his neurotransmitter, which he learned had connections to the dendrite, synapse, and somatic, and thought about how amazing the human brain could be.
The lamp explained it was time for Jason's journey to end for today, but welcomed him to come back soon. Jason was escorted to the same door he had first entered through, and returned to his normal world.
