Does impulse travel faster along myelinated neuron?

Yes, impulse travels faster along myelinated neuron.

Myelin is a fatty substance that insulates the axons of some neurons. It acts like an electrical insulator, preventing the electrical signals from leaking out of the axon. This allows the signals to travel faster and more efficiently.

In unmyelinated neurons, the electrical signals travel more slowly because they have to jump from one node of Ranvier to the next. This is because the myelin sheath is not continuous, but rather is made up of segments that are separated by nodes of Ranvier. The electrical signals have to cross these nodes, which slows down their progress.

In myelinated neurons, the electrical signals travel faster because they do not have to jump across any nodes of Ranvier. The myelin sheath provides a continuous insulation, which allows the signals to travel smoothly and quickly.

Therefore, impulse travels faster along myelinated neuron because the myelin sheath acts like an electrical insulator, preventing the electrical signals from leaking out of the axon and allowing them to travel faster and more efficiently.
