axon

The longest axon in the human body would be those that run from the base of your spine down to your feet, the longest of which probably controls the interosseus muscles which twitch your toes from side to side. It's all one single cell. Cool, huh?

axon: a threadlike structure on which impulses are transmitted away from the main body of a nerve cell [from Greek, axon, axle, axis]. See also dendrite; synapse.
