Reply to comment by FRidgard in ELI5 How can cells (Neuron) have another cell (Schwann's cells) inside them by Original-Cookie4385

The Schwann cell is a separate cell in the periphery nervous system. In the CNS oligodendrocytes do the same job. These cells wrap part of their plasma membrane around the axon of the neuron to aid conduction and we call that part left there the myelin sheath. https://www.ncbi.nlm.nih.gov/books/NBK27954/
