What are three physical characteristics that distinguish axons from dendrites?

Three physical characteristics that distinguish axons from dendrites are:

1. Number: A typical neuron has one axon, which can extend over long distances, while it usually has multiple dendrites that branch out from the cell body.
2. Diameter: Axons generally maintain a uniform diameter along their length, whereas dendrites often taper to a fine point as they extend away from the cell body.
3. Functionality: Axons are primarily responsible for transmitting electrical signals away from the neuron to other neurons or muscles, while dendrites are specialized for receiving incoming signals from other neurons
