Mark,

This is a very good article but the myelin is focused on the Central Nervous System and does not get into the myelin in the Peripheral Nervous System. They are not the same myelins…they are produced from different cells.

[B]CNS: Oligodendrocyte cells[/B] make the myelin, [U][B]they cooperate in the formation of a myelin sheath along the axon[/B][/U], this is the process of myelination. Each oligodendrocyte produces segments of several axons.

[B]PNS: Schwann cells[/B] make the myelin, [U][B]each schwann cell can myelinate one segment of a single axon[/B][/U] and they work together to form the myelin sheath.

Best regards.

Jethro

Thanks CG.

Well said Gene, your supporting words also make wonder like medicine. Simon to note this pl.
