The myelin sheath consists of multiple layers of lipid-rich membranes that wrap around the axons of neurons. These layers are formed by oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. Each layer is composed of a phospholipid bilayer, which provides insulation and increases the speed of electrical signal propagation along the axon. The gaps between these myelin layers, known as Nodes of Ranvier, facilitate the rapid transmission of nerve impulses through saltatory conduction.

What is myelin sheath on nerve fibers?
The endoneurium surrounds and protects the myelin sheath.
State the structure of neurons which reduces leakage of impulses?
Neurons are covered by a myelin sheath, which consists of layers of fatty tissue that insulates the axon and reduces leakage of impulses. The myelin sheath is formed by specialized cells called oligodendrocytes in the central nervous system, and Schwann cells in the peripheral nervous system. This insulation allows for faster and more efficient transmission of electrical impulses along the axon.
What is the sheath of the Schwann Cell also called?
Surrounding the myelin sheath, there is a thin membrane called neurilemmal sheath. This is also called neurilemma or sheath of Schwann. This contains Schwann cells, which have flattened and elongated nuclei. The cytoplasm is thin and modified to form the thin sheath of neurilemma enclosing the myelin sheath. One nucleus is present in each internode of the axon. The nucleus is situated between myelin sheath adn neurilemma. At the node of Ranvier (where myelin sheath is absent), the neurilemma invaginates and runs up to axolemma in the form of a finger like process. In nonmyelinated nerve fiber, the neurilemma continuously surrounds axolemma. Neurilemma is absent in central nervous system. Neurilemma is necessary for the formation of myelin sheath (myelinogeneis).
It insulates the axon of the neuron?
The myelin sheath insulates the axon of a neuron, allowing for faster transmission of electrical signals. This fatty layer helps to speed up the signal conduction by allowing the electrical impulse to jump from one node of Ranvier to the next, a process known as saltatory conduction.

What is the definition of myelin sheath?
A myelin sheath is a layer of myelin (a dielectric, or electric insulator) around the axon of a neuron.

What creates myelin sheath?
Oligodendrocytes are specialized neurolgical cells that produce myelin sheath.
How does a myelin sheath form?
A myelin sheath forms when oligodendrocytes in the central nervous system or Schwann cells in the peripheral nervous system wrap around axons, creating multiple layers of membrane rich in lipids. This myelin sheath acts as an insulating layer that speeds up the transmission of electrical signals along the axon.
What insulates nerve fibers?
Myelin insulation insulates nerve fibers by wrapping around them and forming a protective sheath. This myelin sheath helps to increase the speed of nerve impulse conduction along the nerve fibers.
What is the sheath of a schwann cell called?
myelin sheath
What creates the myelin sheath in the PNS?
Schwann cells make the myelin sheath in the PNS. Each of the Schwann cells myelinate their own segment of the axon, they work together to make the myelin sheath.
