How Fast Does An Impulse Travel In A Myelinated Axon . The ratio of the inner (axon) perimeter to the outer (myelin) perimeter remains constant at or near the optimal value of 0.6 for conduction in all groups of fibres at all periods of atrophy. The myelinated axon is isolated, so that current flow does not leak out of the axon, and the.
Saltatory conduction, which increases the speed of from schoolbag.info
The formation of an action potential can be divided into five steps. (1) a stimulus from a sensory cell or another neuron causes the target cell to depolarize toward the threshold potential. In the absence of a myelin sheath, an impulse path way is that of the dendrite or axon.
