contains neuron cell bodies and unmyelinated gibers. 5 Terms. 1985-04-01 · Numbers of myelinated and unmyelinated axons in the dorsal, lateral, and ventral funiculi of the white matter of the S2 segment of cat spinal cord. Chung K, Sharma J, Coggeshall RE. The present work determines the numbers of myelinated and unmyelinated axons in the dorsal, lateral, and ventral funiculi of the S2 segment of the cat spinal cord. Oligodendrocytes selectively myelinate a particular set of axons in the white matter.

(Axons, which can be up to three feet long, are the longest projections of brain cells and carry a cell’s signal to other cells.) Many axons may be myelinated by multiple processes from a single oligodendrocyte. The white and gray matter of the brain and spinal cord are distinguished by the presence or absence of myelin sheaths: White matter contains the myelinated axons of neurons. (The white color is from the myelin sheaths.

White matter is one of the two components of the central nervous system (CNS). It consists mostly of glial cells and myelinated axons and forms the bulk of the deep parts of the cerebrum and the superficial parts of the spinal cord.

Figure 1.1 shows an illustration of a neuron with dendrites and a myelinated axon. Regions of the brain that are myelinated have a white colour and are therefore termed white matter (WM), while unmyelinated parts of the brain are termed grey matter (GM).

Myelination is  White matter (WM) exclusively contains axons and their glial cell partners including astrocytes, oligodendro- cytes (myelinating and nonmyelinating), and  Axons are made metabolically efficient by myelination, which enables saltatory Furthermore, in white matter MS lesions, oxidative damage to mtDNA has been  White matter does not contain any cell bodies, but mostly contains myelinated nerve (hint - think about how big the axons are - i.e. how big neurons can get  Myelin is lipid-rich, and on gross inspection appears white. Thus, in the 'white matter' of the brain and spinal cord, myelinated axons are the predominant neuronal  The white matter in the brain and spinal cord is due to the high concentration of myelinated axons in that area, due to the white color of the myelin.
