How Fast Does An Impulse Travel In A Myelinated Axon . As such the the speed of the impulse is reduced. The diameter of the myelinated axons is large enough to facilitate a speedy nerve impulse conduction.

A nerve impulse is an electrical phenomenon that occurs because of a difference in electrical charge across the plasma membrane of a neuron. If however, a myelin sheath is present, then the charges of the impulse are transported through the nodes of ranvier, hence at much higher speed than an impulse on a non myelinated neuron. By acting as an electrical insulator, myelin greatly speeds up action potential conduction (figure 3.14).

Myelinated axons are present in. 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. (1) a stimulus from a sensory cell or another neuron causes the target cell to depolarize toward the threshold potential.

Moreover, what structures in a nerve cell are. The answer lies in the simple laws of electricity conduction. This translates to an increased speed in the transmission of the nerve impulse. 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.
