... There are hundreds of dendrites but usually just one axon. Axons can be very long (> 1 m) while dendrites are < 2 mm. Axons have the same diameter the entire length – dendrites taper. Axons have terminals (synapses) and no ribosomes. Dendrites have spines (punching bags). Don’t be fooled by the bran ...
