Action potentials cannot be transported more quickly within the dendrites of neurons thanks to myelin sheaths.
A fatty substance generated by Schwann cells makes up the myelin sheath. This substance stops nerve impulses from moving along the axon. The axon of the nerve cell, not the dendrites, is encircled by the myelin sheath. For saltatory conduction, it is required. The axon of a neuron is encased in myelin. By insulating the axon, it helps to accelerate conduction. Where the myelin sheath surrounds the axon, the action potential cannot arise. Instead, the action potential is transported to the end of the nerve where it can be passed on to the following neuron by the electrical wave generated at each node. Neurons with myelin can communicate up to 20 times faster than neurons without myelin.
