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 does the schwann cell form a myelin sheath around?
Schwann cells form a myelin sheath around peripheral nerve fibers in the peripheral nervous system.
What surrounds the axon?
The axon is surrounded by the myelin sheath, which is a fatty insulating layer that speeds up the transmission of electrical signals. Outside the myelin sheath, there are Schwann cells or oligodendrocytes (depending on the type of neuron) that help form and maintain the myelin sheath.
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 fatty tissue that covers axons and speeds up impulses as they travel from cell to cell?
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?
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.
What does the schwann cell form a myelin sheath around?
Schwann cells form a myelin sheath around peripheral nerve fibers in the peripheral nervous system.

What is myelin sheath on nerve fibers?
The endoneurium surrounds and protects the myelin sheath.
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 are axons surrounded by?
Axons are surrounded by myelin sheath, a fatty material that insulates and protects the axon. Additionally, axons are also surrounded by Schwann cells in the peripheral nervous system and oligodendrocytes in the central nervous system, which help form the myelin sheath.
What creates myelin sheath?
Oligodendrocytes are specialized neurolgical cells that produce myelin sheath.

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).
What surrounds the axon?
The axon is surrounded by the myelin sheath, which is a fatty insulating layer that speeds up the transmission of electrical signals. Outside the myelin sheath, there are Schwann cells or oligodendrocytes (depending on the type of neuron) that help form and maintain the myelin sheath.
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.
