On a molecular level, in the internodes it increases the distance between extracellular and intracellular ions, reducing the accumulation of charges.

The discontinuous structure of the myelin sheath results in saltatory conduction , whereby the action potential "jumps" from one node of Ranvier, over a long myelinated stretch of the axon called the internode, before "recharging" at the next node of Ranvier, and so on, until it reaches the axon terminal.

Once it reaches the axon terminal, this electrical signal provokes the release of a chemical message or neurotransmitter that binds to receptors on the adjacent post-synaptic cell e.

This "insulating" role for myelin is essential for normal motor function i. The process of generating myelin is called myelination or myelinogenesis.

In the CNS, cells called oligodendrocyte precursor cells OPCs; the precursors of oligodendrocytes differentiate into mature oligodendrocytes, which form myelin.

In humans, myelination begins early in the 3rd trimester, [10] although only little myelin is present in either the CNS or the PNS at the time of birth.

During infancy, myelination progresses rapidly, with increasing numbers of axons acquiring myelin sheaths. This corresponds with the development of cognitive and motor skills, including language comprehension, speech acquisition, crawling and walking.

Myelination continues through adolescence and early adulthood and although largely complete at this time, myelin sheaths can be added in grey matter regions such as the cerebral cortex , throughout life.

Myelin is considered a defining characteristic of the jawed vertebrates gnathostomes , though axons are ensheathed by a type of cell, called glial cells, in invertebrates.

Myelin was first described in by Rudolf Virchow , [16] although it was over a century later, following the development of electron microscopy, that its glial cell origin and its ultrastructure became apparent.

In vertebrates, not all axons are myelinated. For example, in the PNS, a large proportion of axons are unmyelinated. Instead, they are ensheathed by non-myelinating Schwann cells known as Remak SCs and arranged in Remak bundles.

CNS myelin differs slightly in composition and configuration from PNS myelin, but both perform the same "insulating" function see above.

Being rich in lipid, myelin appears white, hence the name given to the " white matter " of the CNS.

Both CNS white matter tracts e. Blood vessels provide the route for oxygen and energy substrates such as glucose to reach these fibre tracts, which also contain other cell types including astrocytes and microglia in the CNS and macrophages in the PNS.

The primary lipid of myelin is a glycolipid called galactocerebroside. The intertwining hydrocarbon chains of sphingomyelin strengthen the myelin sheath.

Cholesterol is an essential lipid component of myelin, without which myelin fails to form. The main purpose of myelin is to increase the speed at which electrical impulses propagate along the myelinated fiber.

In unmyelinated fibers, electrical impulses action potentials travel as continuous waves, but, in myelinated fibers, they "hop" or propagate by saltatory conduction.

The latter is markedly faster than the former, at least for axons over a certain diameter. Myelin decreases capacitance and increases electrical resistance across the axonal membrane the axolemma.

It has been suggested that myelin permits larger body size by maintaining agile communication between distant body parts.

Myelinated fibers lack voltage-gated sodium channels along the myelinated internodes, exposing them only at the nodes of Ranvier. Here, they are highly abundant and densely packed.

The resting membrane potential is then rapidly restored due to positively charged potassium ions leaving the axon through potassium channels. The sodium ions inside the axon then diffuse rapidly through the axoplasm axonal cytoplasm , to the adjacent myelinated internode and ultimately to the next distal node of Ranvier, triggering the opening of the voltage gated sodium channels and entry of sodium ions at this site.

Although the sodium ions diffuse through the axoplasm rapidly, diffusion is decremental by nature, thus nodes of Ranvier have to be relatively closely spaced, to secure action potential propagation.

Whilst the role of myelin as an "axonal insulator" is well-established, other functions of myelinating cells are less well known or only recently established.

The myelinating cell "sculpts" the underlying axon by promoting the phosphorylation of neurofilaments , thus increasing the diameter or thickness of the axon at the internodal regions; helps cluster molecules on the axolemma such as voltage-gated sodium channels at the node of Ranvier; [26] and modulates the transport of cytoskeletal structures and organelles such as mitochondria , along the axon.

When a peripheral fiber is severed, the myelin sheath provides a track along which regrowth can occur. However, the myelin layer does not ensure a perfect regeneration of the nerve fiber.

Some regenerated nerve fibers do not find the correct muscle fibers, and some damaged motor neurons of the peripheral nervous system die without regrowth.

Damage to the myelin sheath and nerve fiber is often associated with increased functional insufficiency. Unmyelinated fibers and myelinated axons of the mammalian central nervous system do not regenerate.

Sufferers of pernicious anaemia can also suffer nerve damage if the condition is not diagnosed quickly. Subacute combined degeneration of spinal cord secondary to pernicious anaemia can lead to slight peripheral nerve damage to severe damage to the central nervous system, affecting speech, balance, and cognitive awareness.

When myelin degrades, conduction of signals along the nerve can be impaired or lost, and the nerve eventually withers. The immune system may play a role in demyelination associated with such diseases, including inflammation causing demyelination by overproduction of cytokines via upregulation of tumor necrosis factor [32] or interferon.

Demyelination results in diverse symptoms determined by the functions of the affected neurons. It disrupts signals between the brain and other parts of the body; symptoms differ from patient to patient, and have different presentations upon clinical observation and in laboratory studies.

Research to repair damaged myelin sheaths is ongoing. Techniques include surgically implanting oligodendrocyte precursor cells in the central nervous system and inducing myelin repair with certain antibodies.

While results in mice have been encouraging via stem cell transplantation , whether this technique can be effective in replacing myelin loss in humans is still unknown.

Increasing cholinergic stimulation also may act through subtle trophic effects on brain developmental processes and particularly on oligodendrocytes and the lifelong myelination process they support.

Increasing oligodendrocyte cholinergic stimulation, AChEIs , and other cholinergic treatments, such as nicotine , possibly could promote myelination during development and myelin repair in older age.

Dysmyelination is characterized by a defective structure and function of myelin sheaths; unlike demyelination, it does not produce lesions.

Such defective sheaths often arise from genetic mutations affecting the biosynthesis and formation of myelin. The shiverer mouse represents one animal model of dysmyelination.

Human diseases where dysmyelination has been implicated include leukodystrophies Pelizaeus—Merzbacher disease , Canavan disease , phenylketonuria and schizophrenia.

Functionally equivalent myelin-like sheaths are found in several invertebrate taxa including oligochaetes , penaeids , palaemonids , and calanoids.

These myelin-like sheaths share several structural features with the sheaths found in vertebrates including multiplicity of membranes, condensation of membrane, and nodes.

In contrast, nodes found in the sheaths of invertebrates are either annular or fenestrated; i. From Wikipedia, the free encyclopedia. Fatty substance that surrounds nerve cell axons to insulate them and increase transmission speed.
