Myelin is a fatty substance that forms a protective sheath around nerve fibers, helping to increase the speed and efficiency of nerve signal transmission. It is produced by specialized cells called oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. Its waxy appearance comes from its high lipid content.
Myelin is a fatty substance that forms a protective sheath around nerve fibers. It acts as insulation, allowing for faster transmission of electrical signals along the nerve cells. Damage to myelin can result in neurological disorders such as multiple sclerosis.
insulating layer called myelin sheath. This myelin sheath helps to speed up the conduction of electrical impulses along the axon by allowing the impulse to jump between nodes of Ranvier, known as saltatory conduction.
InformationThe white matter of the brain contains nerve fibers. Many of these nerve fibers (axons) are surrounded by a type of fat called myelin. The myelin gives the whitish appearance to the white matter. Myelin acts as an insulator, and it increases the speed of transmission of all nerve signals.
The diameter of the nerve fiber and the presence or absence of a myelin sheath are the two main factors that affect the speed of nerve signals. Larger diameter fibers and a myelin sheath help to increase the speed of nerve signal conduction.
Myelin is a fatty substance that wraps around the axon of a neuron, acting as an insulator that speeds up the transmission of electrical signals. By insulating the axon, myelin helps the signals propagate more efficiently and quickly along the neuron.
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.
Myelin is the material that covers the spinal cord. It protects the cord from damage. If the myelin wears away, then a person is said to have Multiple Sclerosis.
The white lipid material that insulates the axon of a neuron is called myelin. In the central nervous system, myelin is created by oligodendrocytes while in the peripheral nervous system the myelin is created by Schwann cells. The purpose of myelin is to speed up action potentials. It's important to know that the myelin does not coat the axon entirely; each sheath of myelin is separated by a gap, called a node of Ranvier. These gaps are responsible for the quick transport of action potentials, due to the fact that the potentials can "jump" from node to node rather than having to travel down the entire length of the axon (this is called saltatory conduction).
Myelin is the material that surrounds and protects the spinal cord, and it helps conduct information signals up and down the cord. Myelin is rich in protein.
The material surrounding the axon that increases the speed of the nerve impulse is called myelin. Myelin is a fatty substance that acts as an insulating layer, allowing for faster transmission of electrical signals along the axon.
Axons are coated in a fatty substance called myelin - a "myelin sheath". It insulates and protects the cell body of neurones. The myelin doesn't completely coat the axon: there are small gaps between the myelin, called the nodes of Ranvier.

The myelin sheath is composed of lipid material and covers axons.
The fatty tissue that covers axons and speeds up impulses is called myelin. Myelin acts as an insulating layer, which helps to increase the speed and efficiency of nerve impulse transmission along the axon.
The layer of lipid around an axon is called myelin sheath. It acts as an insulator, allowing for faster transmission of nerve impulses along the axon.
Myelin is a fatty substance that forms a protective sheath around nerve fibers. It acts as insulation, allowing for faster transmission of electrical signals along the nerve cells. Damage to myelin can result in neurological disorders such as multiple sclerosis.
The insulating material produced by Schwann cells is known as myelin. Myelin forms a protective covering around nerve fibers, allowing for faster transmission of nerve impulses. This insulation is critical for proper functioning of the nervous system.
