pus . gray matter areas of the nervous system where the nerve fibers are unmyelinated (not enveloped by a myelin sheath ) ; it contains the bodies of the nerve cells. Tissue composed of myelinated fibers is called white The structure of the spinal cord can be described as (1) composed of thirty-one segments (2) having a cervical enlargement and a lumbar enlargement (3) a central core of gray matter that is surrounded by white matter (4) having gray matter that is Because up to half of the white matter may be composed of myelin, it is unsurprising that the brain is the most cholesterol-rich organ in the body. The concentration of cholesterol in the brain, and particularly in myelin, is consistent with an essential function related to its membrane properties.

MS is predominantly a disease of the white matter in the CNS. About 95% of all lesions associated with MS occur in the white matter. The first suggestion that matter is composed of atoms is attributed to the Greek philosophers Leucippus and Democritus, who developed their ideas in the 5th century BCE. However, it was not until the early nineteenth century that John Dalton (1766–1844), a British schoolteacher with a keen interest in science, supported this hypothesis with quantitative measurements. 2018-08-23 · White matter, on the other hand, is mainly composed of long-range myelinated axons (that transmit signals to the grey matter) and very few neuronal cell bodies. White matter definition, nerve tissue, especially of the brain and spinal cord, which primarily contains myelinated fibers and is nearly white in color. See more. White Matter.

White matter is tissue in the brain composed of nerve fibers. The fibers (called axons) connect nerve cells and are covered by myelin (a type of fat). The myelin is what gives white matter its white color.

White matter is composed of bundles of myelinated axons, which connect various gray matter areas of the brain to each other, and carry nerve impulses between neurons.

Problem 4TY from Chapter 43: The white matter of the CNS is composed of. Get solutions It is composed of nerve cell processes, i.e. extensions (axons), which connect various grey matter areas of the brain to each other and carry nerve impulses to and from the nerve cell bodies within the central nervous system (neurons). Cerebral and spinal white matter does not contain dendrites. The axons of white matter transmit signals from various grey matter areas (the locations of nerve cell bodies) of the cerebrum to each other and carry nerve impulses between neurons. While grey matter is primarily associated with processing and cognition, white matter modulates the distribution of action potentials, acting as a relay and coordinating communication between different brain regions.

The white matter is composed of nerve fibers carrying ascending and descending information and makes up the outer regions of the cord. The gray matter, which contains cell bodies, is located in the center of the cord and is easily identified by its color and butterfly shape. gray matter: [ mat´er ] 1. physical material having form and weight under ordinary conditions; called also substance . 2.
