There are two main types of neurons in the body- myelinated and unmyelinated. Myelinated neurons are covered in a fatty sheath called myelin, which helps them transmit signals quickly and efficiently. Unmyelinated neurons lack this protective coating, which can make them slower to respond. Though both types of neurons are necessary for normal functioning, there are some key differences between them. Here we’ll take a look at what makes myelinated neurons special, and how they differ from unmyelinated cells.
What is a Myelinated Neuron?
Myelinated neurons are neurons that have a myelin sheath. Myelin is a lipid-rich substance that surrounds the axon of some nerve cells and forms an electrically insulating layer. Myelinated neurons are found in the central and peripheral nervous systems.
- The myelin sheath helps to increase the speed of nerve impulses by reducing electrical resistance along the axon. Myelinated neurons are also known as saltatory conduction because nerve impulses “jump” from one node of Ranvier to the next.
- Myelinated neurons are important for tasks that require fast reactions, such as motor control. unmyelinated neuron, on the other hand, has no myelin sheath. The myelin sheath is produced by oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system.
- Myelin is made up of lipids, including cholesterol, and proteins, including myelin basic protein (MBP). Myelin helps to increase the speed of nerve impulses by reducing electrical resistance along the axon.

What is Unmyelinated Neuron?
Unmyelinated neurons are a type of nerve cell that do not have a myelin sheath. This sheath is an insulating layer that helps to protect and speed up the transmission of electrical signals. Unmyelinated neurons are found in the peripheral nervous system, which includes all of the nerves that are outside of the brain and spinal cord. These neurons are smaller and shorter than myelinated neurons, and they conduct electrical signals more slowly. However, they are able to adapt and change their firing patterns more easily than myelinated neurons. As a result, unmyelinated neurons play an important role in helping the body to respond to new situations and stimuli.

Conclusion
So what does this mean for you as a consumer? The next time you’re looking to purchase a high-end product, or even just considering it, keep in mind that the more expensive option may be worth the investment. Not only is your brain getting a workout trying to make the decision, but the manufacturer has likely put a lot of thought (and money) into ensuring that its product looks and feels luxurious.
