The cell bodies of neurons controlling your feet are actually located in your spine. The cell body is where they make peptides such as the ones in this simulation. Their axons can be a meter long, traveling out to the tips of your toes (about 1,000 times as long as the 60 µm axon in the simulation). Do you think these neurons use diffusion to move peptides from the cell body to the axon tip? Explain your reasoning
