How Fast Does An Impulse Travel In A Myelinated Axon . A nerve impulse is transmitted to another cell at either an electrical or a chemical synapse. (1) a stimulus from a sensory cell or another neuron causes the target cell to depolarize toward the threshold potential.

The white matter is the sensory part of our brain, and its apparent brightness is due to the high density of myelin sheaths. On fibers that allow the nerve to travel faster can reach speeds of over 200 miles. As such the the speed of the impulse is reduced.

In the absence of a myelin sheath, an impulse path way is that of the dendrite or axon. The diameter of the myelinated axons is large enough to facilitate a speedy nerve impulse conduction. All along the axon you’ve got fat molecules that create little spaces in the axon which are not isolated, those are called nodes of ranvier. Myelinated axons are required in cells where quick response is required.
