Science glossary film: Axon

The long projecting part of a nerve cell that transmits impulses away from the body of the nerve cell to the synapse at its tip. The longest axons in the human body can be over a metre long, for example, connecting the big toe to the spinal cord, making these neurons the largest cells in the body.
