AI Summary

All cells, whether big or small, short or long, rely on proteins to function properly. In most cells, transporting these proteins is relatively simple. Neurons in the brain, however, face a significant logistical challenge because their axons, the thread-like structures that carry electrical impulses, can extend for meters. As a result, essential materials produced in the cell body must travel enormous distances to reach the ends of axon terminals.
