Yes, impulses travel faster in myelinated axon rather than in unmyelinated. It is mostly due to nodes of Ranvier. Instead of travel along the axon, in myelinated axon impulses "jump" from node to node.
Also there are two types of myelinated axons: type A and type B. (Type C in unmyelinated axon.) Type A is the fastest among all of them.
What else can I help you with?
What travels through the neuron?
An electrical impulse will travel through a neuron.
Would conduction speed of a nerve fiber be the fastest in a large or small myelinated fiber?
The conduction speed of a nerve fiber is fastest in large myelinated fibers. This is because myelin acts as an insulator, allowing for faster propagation of the action potential by saltatory conduction in large fibers compared to small unmyelinated fibers.
Why are nerves myelinated?
Nerves are myelinated to increase the speed of nerve impulse conduction. The myelin sheath acts as insulation, helping the nerve signal to travel faster along the axon. This allows for more efficient communication between different parts of the body.

At what speed are nerve impulses conducted in myelinated and unmyelinated neurons?
In thick well insulated (myelinated) neurones the impulse can travel in excess of 100m/s. In unmyelinated neurones the impulse can be conducted at less than 1m/s
How long does it take for an impulse to travel from one neuron to another?
one second
What is a neuron identify the parts of the neuron and their functions?
there's the axon (the nerve) the electrical impulse goes down that and covering the axon is the myelin sheath, otherwise known as a fatty sheath which insulates and helps make the electrical impulse go faster. In between each myelin sheath there are synapses (gaps between each one) and the impulse has to cross the gap so neurotransmitters are released which bind to receptors on the other side creating another electrical impulse which makes it travel even faster.
What is the function of the dentrites?
Dendrites are attaches to the axon terminals of other neurons. The nerve impulse travel from other neurons into the corresponding neuron via dendrites.
What is impulse conduction is fastest in neurons?
Impulses that travel along myelinated neurons are the fastest.
How nervous impulse travel in body and diagram?
Nervous impulses travel along neurons through a process called action potential, which occurs when a neuron is stimulated by an external signal. This stimulation causes sodium ions to flow into the neuron, leading to a rapid change in electrical charge that propagates along the axon to the synapse. At the synapse, neurotransmitters are released to transmit the signal to the next neuron. A simple diagram would illustrate a neuron with labeled parts: dendrites, cell body, axon, and synaptic terminal, showing the direction of impulse travel.
What is released when an impulse reaches the end of a neuron?
The impulse ends in the terminal or synaptic knob. Here neurotransmitters are put in vesicles and travel across the synaptic cleft to the next neuron.
What is the fatty tissue that helps the impulse move faster as they travel from cell to cell?
The Myelin sheath
