Myelinated axons in the central nervous system

Axons are described as either un-myelinated or myelinated. Myelin is a layer of a fatty insulating substance, which is formed by two types of glial cells: Schwann cells en-sheathing peripheral neurons and oligodendrocytes insulating those of the central nervous system. SYNAPTIC MECHANISMS Myelinated, synapsing cultures of murine spinal cord – validation as an in vitro model of the central nervous system C. E. Thomson,1 M. McCulloch,2 A. Sorenson,3 S. C These multiple, interrelated roles of Contactin in central myelin extend beyond Contactin’s reported function in paranodal junction formation in the peripheral nervous system (PNS) , and highlight its key role in the communication between axons and oligodendrocytes that enable efficient formation of functional myelin in the CNS. The nervous system is perhaps the most important part of the body. The roles it serves are crucial for perceiving and responding to the world around us. Our nervous systems allow our body to respond to stimuli and coordinate important bodil Create your free account Already have an account?

These cells surround and protect axons, long projections of a nerve cell, Centrala nervsystemet (CNS) består av hjärnan och ryggmärgen. Perifera Myelin, isolerar axon och möjliggör saltatorisk fortledning av the nerve fibres of the central and peripheral nervous systems of many animals. Nerve Myelin is a layered tissue surrounding the axons or nerve fibers.

In the central nervous system the myelin sheath is provided by another type of glial cell, the oligodendrocyte. Schwann cells myelinate a single axon. An oligodendrocyte can myelinate up to 50 axons. The composition of myelin is different in the two types. In the peripheral nervous system Schwann cells form the myelin sheath of a myelinated axon. In the central nervous system oligodendrocytes form the insulating myelin.
