Myelin sheath and nodes
The covering of a fatty material that speeds up the passage of a nerve impulse is called the myelin sheath. It is made of lipids and proteins and acts as an insulating layer around the axon of a neuron, allowing for faster transmission of electrical signals.
Synapses are the part of the nervous system that coordinates the passage of nerve impulses. They are the junctions between neurons.

Yes, an action potential is needed for a nerve impulse to occur.

It is called a nerve impulse.
Neurotransmitters in a neuron allow a nerve impulse to be transmitted from one neuron to another by crossing the synapse and binding to receptors on the receiving neuron. This triggers an electrical or chemical signal to continue the nerve impulse along the neural pathway.
When the nerve impulse encounters a myelin-covered section of a neuron, it jumps between the nodes of Ranvier, allowing for faster transmission speed due to saltatory conduction. Myelin acts as an insulator, preventing the impulse from dissipating and increasing the efficiency of signal transmission along the neuron.
