An impulse relayed along a myelinated axon "jumps" from Node of Ranvier to Node Ranvier. Axons insulated by a Myelin sheath are able to conduct impulses faster than those not so insulated. Schwann cells are types of cells that makes up the myelin sheath of a motor neuron. An impulse moves toward a neuron's cell body along Dendrites.

Bruh i don’t know the answer tbh but you can google it
