A neuron walks into a bar and does not order a drink because the cerebellum, the part of the brain responsible for providing precise timing for skeletal muscle activity and controls our balance, is easily sedated with alcohol, and the liver, the organ responsible for processing alcohol, is easily damaged by it. Instead, he orders an axon because his was injured when the person who's brain he occupies hit their head very hardly in an accident and the neuron's axon was broken off. The bartender, a Schwann Cell, rebuilds his axon. The neuron thanks the schwann cell, and an oligodendrocyte walks up to him. "Did you want that axon myelinated sir?" The Neuron obliges, and he uses this increased myelin to increase the speed of future action potentials.

Neuron: Man I really wish my axon was myelinated rn

The Humble Oligodendrocyte:
