Why does the myelin sheath have gaps in it?
Because the sheath is produced by several Schwann cells that arrange themselves end to end along the nerve fiber, each Schwann cell forms only one part of the tiny segment of the sheath.
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 type of neuroglia forms the myelin sheath?
oligodendrocytes for C.N.S. and shcwann cells for P.N.S.
What is ligule?
The ligule is part of the leaf that is found at the junction of the blade and sheath of the leaf. It may take several forms, but it is commonly some form of translucent membrane or a fringe of hairs.
The area that forms around a volcanoes central opening?
A bowl-shaped area that forms around a volcano's central vent is called a crater.

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 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 fatty tissue that covers axons and speeds up impulses as they travel from cell to cell?
That substance is called the myelin cell or myelin sheath.
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'.
The tightly wound cell membrane around the axon forms the myelin sheath and as acts as what?
jesus save me
What type of neuroglia forms the myelin sheath?
oligodendrocytes for C.N.S. and shcwann cells for P.N.S.
Are muscles and glands myelinated?
Muscles and glands are not myelinated. It is the axon of a neuron that is myelinated. The myelin forms a layer called myelin sheath that makes the nervous system function properly.
What is the membrane covering the brain and spinal cord called?
The myelin sheath forms a protective layer over nerves. However, it is not present on all nerves. Retinal nerves for instance normally are devoid of myelin.
What are nerves and muscle fibers?
A nerve fiber is a threadlike extension of a nerve cell and consists of an axon andmyelin sheath (if present) in the nervous system. There are nerve fibers in the central nervous system and peripheral nervous system. A nerve fiber may be myelinated and/or unmyelinated. In the central nervous system (CNS), myelin is produced byoligodendroglia cells. Schwann cells form myelin in the peripheral nervous system (PNS). Schwann cells can also make a thin covering for an axon which does not consist of myelin (in the PNS). A peripheral nerve fiber consists of an axon, myelin sheath, Schwann cells and its endoneurium. There are no endoneurium and Schwann cells in the central nervous system. A myocyte (also known as a muscle cell or muscle fiber) [1] is the type of cell found inmuscle tissue. They are long, tubular cells that arise developmentally from myoblasts to form muscles in a process known as myogenesis. [2] There are various specialized forms of myocytes: cardiac, skeletal, and smooth muscle cells, with various properties. Cardiac myocytes are responsible for generating the electrical impulses that control the heart rate, among other things
Myelin?
DefinitionMyelin is an insulating layer that forms around nerves, including those in the brain and spinal cord. It is made up of protein and fatty substances. The purpose of the myelin sheath is to allow rapid and efficient transmission of impulses along the nerve cells. If the myelin is damaged, the impulses slow down. This can cause diseases like multiple sclerosis.
Why does increasing the axon diameter also increase the speed of impulse conduction?
Larger diameter axons conduct impulses more rapidly than axons with a smaller diameter. Larger axons tend to be myelinated and conduct impulses rapidly. Myelin is a substance rich in lipid that forms an electrical insulation layer around the axon. This insulating myelin sheath allows impulses to be transmitted more rapidly then small diameter axons that are nonmyelinated.
