How Fast Does The Signal Travel Down The Axon? Smaller fibers without myelin, like the ones carrying pain information, carry signals at about 0.5-2.0 m/s (1.1-4.5 miles per hour). The fastest signals in our bodies are sent by larger, myelinated axons found in neurons that transmit the sense of touch or proprioception – 80-120 m/s
Do Myelinated Axons Use More Energy? Do myelinated axons use more energy? The added bulk of the myelin allows 13 unmyelinated axons of same diameter to fit in the volume of one myelinated fibre, suggesting that the ratio of energy demand over wiring density is 5 times higher for myelinated fibers vs unmyelinated axons. Why
Does Myelination Increase Time Constant? Does myelination increase time constant? The myelin effectively reduces the Cm and increases Rm to decrease time constant and increase length constant if one was to compare an unmyelinated axon and myelinated axon of the same diameter. How does myelination affect the time constant? How does myelin affect the time
Does A Nerve Impulse Travel Faster With Myelin Or Without It? Does a nerve impulse travel faster with myelin or without it? By jumping from node to node, the impulse can travel much more quickly than if it had to travel along the entire length of the nerve fibre. Myelinated nerves can transmit a signal
