Neurons transmit information using the sodium/potassium channels. Basically the influx of these ions across the membrane causes the voltage to increase from its resting potential and this transmits a signal through neuron cells.
These cells can be myelinated or unmyelinated. Myelinated cells just mean it has a protective sheath covering it. (Schwann cells). There are gaps between these cells which causes this electrical signal to "jump" from node to node. This makes the signal run through the body quicker.
An interesting fact: The brain cells are unmyelinated. This means it needs more energy to transmit information and is actually why your brain is the organ that uses up the most ATP (or energy) in your body. Also, because it is unmyelinated, the brain appears grey - thus "grey matter". Myelinated cells are usually white-ish.

Do neuron transfer information in the form of an electrical impulse?
Yes, neurons transfer information in the form of electrical impulses called action potentials. These impulses travel along the neuron's axon to transmit information between neurons.
Basic unit of nervous system?
The basic unit of the nervous system is the neuron. Neurons are specialized cells that transmit signals in the form of electrical impulses to communicate information throughout the body. They have a cell body, dendrites to receive signals, and an axon to transmit signals.
What is A specialized that can receive and transmit signals to other cells like it called?
A specialized cell that can receive and transmit signals to other cells like it is called a neuron. Neurons are the basic building blocks of the nervous system and are responsible for transmitting information throughout the body through electrical and chemical signals.
What is the difference between reLAy neuron and motor neuron?
A relay neuron, also known as an interneuron, helps to transmit signals between sensory and motor neurons in the central nervous system. In contrast, a motor neuron is responsible for transmitting signals from the central nervous system to muscles or glands, resulting in movement or secretion. Relay neurons process and integrate information, while motor neurons directly stimulate muscle contractions.
What is the major function of neuron in nervous system?
Neurons are specialized cells in the nervous system that transmit electrical and chemical signals between different parts of the body. They play a key role in processing and transmitting information, enabling communication within the nervous system and allowing for various functions such as sensation, movement, and cognition.
