42 Which Description Best Matches the Location of White Matter

Many of these nerve fibers are surrounded by a type of sheath or covering called myelin. Diffusion MRI fiber tractography Xue et al 1999 Conturo et al 1999 offers unprecedented insight into the structural connections of the human brainIn a process that parallels post-mortem microdissection tractography in combination with a set of rules constraints and procedures to dissect and segment major white matter fascicles of the.

The myelin is what gives white matter its white color.

. White matter is tissue in the brain composed of nerve fibersThe fibers connect nerve cells and are covered by myelin. Which description best matches the location of white matter. The fibers called axons connect nerve cells and are covered by myelin a type of fat.

QUESTION 92 Which description best matches the location of white matter. Gray matter consists of all parts of neurons and white matter is mostly glial cells. The myelin sheets present in the white matter greatly attribute to its white color while the neuronal cell bodies and the capillaries in the gray matter are responsible for its pinkish gray color.

White matter in the spinal cord is sometimes called. White matter is tissue in the brain composed of nerve fibers. White matter is named for its relatively light.

The brain and the spinal cord consist of nerves that belong to the central nervous systemThe major function of the central nervous system is to coordinate the functions of the body based on the information carried by the peripheral. White matter and grey matter are two components in the brain and the spinal cord. Experts are tested by Chegg as specialists in their subject area.

Gray matter named for its pinkish-gray color is home to neural cell bodies axon terminals and dendrites as well as all nerve synapses. In both the brain and spinal cord white matter is superficial. Cells of the white matter are longer than gray matter cells.

The cerebellum is structured in a similar manner as the cerebrum with a superficial mantle of cerebellar cortex deep cerebellar white matter called the arbor vitae and aggregates of grey matter surrounded by deep cerebellar white matter dentate nucleus globose nucleus emboliform nucleus and fastigial nucleus. Such declines in function are what many people commonly associate with old age. Long thought to be passive tissue white matter affects learning and brain functions modulating the distribution of action potentials acting as a relay and coordinating communication between different brain regions.

Gray matter areas of the nervous system where the nerve fibers are unmyelinated not enveloped by a myelin sheath. Gray matter consists of cell bodies and dendrites whereas white matter consists mostly of myelinated axons. C In both the brain and spinal cord white matter is deep.

Main Difference White Matter vs Grey Matter. White matter is found in the deeper tissues of the brain subcortical. The myelin is what gives white matter its white color.

White matter disease usually occurs due to aging but it can also affect young people. Biology questions and answers. The total length of white matter lessens with age but.

Noun neural tissue especially of the brain and spinal cord that consists largely of myelinated nerve fibers bundled into tracts has a whitish color and typically underlies the cortical gray matter. In the spinal cord white matter is deep while cerebral white matter is superficial. Amyloid beta Aβ plaque accumulation is a pathological hallmark of Alzheimers disease AD and has been associated with alterations in white matter WM microstructure 1 2 with the first being quantified in vivo by positron emission tomography PET and the latter measured on magnetic resonance imaging MRI using diffusion tensor.

This tissue contains millions of. White matter refers to areas of the central nervous system that are mainly made up of myelinated axons also called tracts. D In the spinal cord white matter is superficial while cerebral white matter is deep.

A In both the brain and spinal cord white matter is superficial. This brain tissue is abundant in the cerebellum cerebrum and brain stem. White matter of the brain.

White matter disease or leukoaraiosis involves the degeneration of the brains white matter. It contains the bodies of the nerve cells. Gray matter consists of bundles of axons and white matter consists of groups of cell bodies and dendrites.

The white matter is slightly more prominent 60 than gray matter 40 in the quantity. It also forms a butterfly-shaped portion of the central spinal cord. Myelin gives the white matter its color.

B In the spinal cord white matter is deep while cerebral white matter is superficial. These disruptions could then lead to functional deficits in turn contributing to behavioral impairments. Gray matter- White matter Corpus cal.

Grey Matter in the Brain and Spinal Cord. Myelin speeds up the signals between the cells enabling the brain cells to quickly send and receive messages. View the full answer.

Aside from filling in the deep sections of the brain white matter is also abundant in the superficial areas of the spinal cord. Physical material having form and weight under ordinary conditions. Gray matter forms the processing units of sensory function while white matter forms the connections among gray matter units.

In both the brain and spinal cord white matter is deep. We review their content and use your feedback to keep the quality high. The description best matches the location of white matter - D In the spinal cord white matter is superficial while cerebral white matter is deep.

Indicate which structures and functions describe the white matter of the brain and which describe the gray matter. White matter disease is a disease that affects the nerves that link various parts of the brain to each other and to the spinal cord. The fluid-filled cerebral ventricles lateral.

White matter disease is the wearing away of tissue in the largest and deepest part of your brain that has a number of causes including aging. Tissue composed of myelinated fibers is called white matter. It contains nerve fibers axons which are extensions of nerve cells neurons.

The hypothesis suggests that white matter lesions may lead to disrupted structural connectivity within the brain along what are known as neural tracks.
