axons of neurons in the peripheral nervous system. The myelin sheath helps to insulate the axon and improve the speed of electrical signal conduction along the neuron. Schwann cells are also involved in nerve regeneration and support neuron function within the peripheral nervous system.

What type of neuroglia forms the myelin sheath?
oligodendrocytes for C.N.S. and shcwann cells for P.N.S.
The insulating material produced by Schwann cells is known as what?
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.
Why does the myelin sheath have gaps in it?
The gaps in the myelin sheath, known as Nodes of Ranvier, are necessary for the proper conduction of nerve impulses. They allow for a faster transmission of electrical signals along the axon by allowing the action potential to "jump" from one node to the next, a process called saltatory conduction. This increases the speed and efficiency of nerve impulse transmission.
Is myelin a connective tissue?
No, myelin is not a connective tissue. Myelin is a lipid-rich material that forms a protective sheath around nerve fibers in the central and peripheral nervous systems. It is essential for the proper functioning of the nervous system by insulating and speeding up the transmission of nerve impulses.
What tissue forms the inner lining of a hair follicle?
The inner lining of a hair follicle is formed by the inner root sheath, which is made up of epithelial tissue. This sheath helps to protect and nourish the growing hair shaft as it develops within the follicle.
The schwann cell forms a Myelin Sheath around what part of the nerve?
The Schwann cell forms a myelin sheath around the axon of the nerve.
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 type of neuroglia forms the myelin sheath?
oligodendrocytes for C.N.S. and shcwann cells for P.N.S.
What forms myelin sheath?
The glial cells: oligodendrocytes for central nervous system and schwann cells for peripheral nervous system.
The insulating material produced by Schwann cells is known as what?
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.
What is the name of the cell that forms the myelin sheath around neuron axons?
The cells that are thought to enable myelination to take place are called Glial Cells, which wrap themselves around the axions in a spiral fashion. This creates a sheath, or insulation, around the axion. It is often referred to as 'White Matter'.
Why does the myelin sheath have gaps in it?
The gaps in the myelin sheath, known as Nodes of Ranvier, are necessary for the proper conduction of nerve impulses. They allow for a faster transmission of electrical signals along the axon by allowing the action potential to "jump" from one node to the next, a process called saltatory conduction. This increases the speed and efficiency of nerve impulse transmission.
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 tightly wound cell membrane around the axon forms the myelin sheath and as acts as what?
The myelin sheath acts as an insulator, allowing for faster transmission of electrical impulses along the axon. It also helps maintain the integrity and protection of the axon.
What best describes the waxy-appearing material called myelin?
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.
What best describes the myelin?
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.
Is myelin a connective tissue?
No, myelin is not a connective tissue. Myelin is a lipid-rich material that forms a protective sheath around nerve fibers in the central and peripheral nervous systems. It is essential for the proper functioning of the nervous system by insulating and speeding up the transmission of nerve impulses.
