Once myelinated, the long-term integrity of axons depends on glial supply of metabolites and neurotrophic factors. We have examined the localization of contactin-associated protein (Caspr), the Shaker-type potassium channels, Kv1.1 and Kv1.2, their associated beta subunit, Kvbeta2, and Caspr2 in the myelinated fibers of the CNS. Caspr is localized to the paranodal axonal membrane, and Kv1.1, Kv1.2, Kvbeta2 and Caspr2 to the juxtaparanodal membrane. Myelin sheaths are formed by Schwann cells in the peripheral nervous system and oligodendrocytes in the central nervous system. 1. 2. 3.

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.

With these they can myelinate multiple axons by spiraling around them to form a myelin sheath. Myelinated axons are required in cells where quick response is required. Myelinated axons are present in sensory neurons and motor neurons. But all the motor neurons are not myelinated. Some are unmyelinated as well. Motor neurons of the somatic nervous system are myelinated and the motor neurons of the upper motor neurons are myelinated.

The Schwann cell wraps around the axon to envelop it in a myelin sheath that functions as an electrical insulator. Central nervous system consists of the brain and spinal cord. It is composed entirely of neurons, their axons and dendrites, and the supporting cells of the central nervous system. Macroscopically, central nervous sytem is made up of gray and white matter (substantia grisea et alba). Myelin.

The main function of myelin is to protect and insulate these axons and enhance their transmission of electrical impulses. 1982-04-01 · Cell Biology International Reports, Vol. 6, No. 4, April 1982 401 COATED MICROVESICLES IN CENTRAL NERVOUS SYSTEM MYELINATED AXONS D.

The white matter mostly contains myelinated axons and dendrites of neurons.

Motor neurons of the somatic nervous system are myelinated and the motor neurons of the upper motor neurons are myelinated. Microvesicles of the type observed in the myelinated axons are common in the vesicles of the Golgi apparatus of the cell body and at nerve terminals. In the axoplasm, they are found as b1ebbing profiles associated with axoplasmic smooth endoplasmic reticulum and the plasma membrane.
