How fast does a nerve impulse travel?
Quick Answer
Nerve impulses can travel from a few meters per second in unmyelinated fibers to over 100 meters per second in heavily myelinated ones. Speed depends on fiber size and myelin.
The Full Story
Different neurons conduct signals at very different speeds. Thin, unmyelinated fibers are much slower, while large myelinated axons can transmit impulses very quickly because the signal jumps between nodes of Ranvier. This speed matters for reflexes, coordination, and rapid sensation. Human nerve conduction is one reason the body can react quickly to the environment.
Key Facts
1.Some axons conduct at over 100 m/s
2.Myelin greatly increases speed
3.Faster conduction helps reflexes and coordination
