Do the pyramids consist of gray or white matter?
White matter
How does the degereration of the myelin sheaths on cells in the white matter of the central nervous system result in the impaired brain functions in ALD patients?
Myelin sheaths in the central nervous system do the same basic job as they do in the peripheral nervous system. They insulate the axons, which are the conducting parts of nerve cells, so that they can carry their signal better. When this protective mechanism is damaged, as in ALD, the nerve cells cannot communicate properly and result in the signs and symptoms of ALD. Unfortunately this genetic disorder not usually caught in its early stages to provide effective treatment.
How do you account for difference grey matter white matter?
one's grey and one's white.....they're both matter though...
Is the gray matter deep to white matter?
no the report says normal gray white differentiation
What does gray matter lack that white matter has?
Myelination
Is the myelin sheath white?
Yes. You are right. White matter of brain is mainly composed of myelin sheaths, which surround the axons and gray matter is composed of nerve cell bodies.
What does the cerebral cortex compose of?
The cerebral cortex is composed of neuron cell bodies which lack the fatty white myelin sheaths around the axons and so is sometimes referred to as gray matter.
Why is the white matter of the spinal cord white?
Because it contains a lot of axons with their fatty myelin sheaths. The fat is white.
White matter of brain composed?
myelinated axon of the neurons
What makes brain matter white?
The myelin sheaths found on axons in the brain ("myelinated axons") gives most brain tissue a white color (= "white matter"). The grey, unmyelinated sell bodies, or "soma," of these axons reside in areas of the brain commonly referred to as "grey matter." Ben
What is the orientation of gray and white matter in the brain?
gray matter is composed of neuron cells and is concentrated in the cerebral cortex and nuclei and basal ganglia. white matter is composed ofneuron processes which form tracts connecting parts of the brain with each other and with the spinal cord.
What is Gray matter on the surface of cerebral hemisphere?
Grey matter is the neural cells of the brain. White matter is the axon fat which surrounds the nerves in sheaths for protection. Grey matter can also be spelt Gray matter and the name comes from the simple appearance and the colour of the brain's lobes.
Does the white dwarf have a rocky surface or a gaseous?
Neither. A white dwarf is composed of matter in an entirely different state called electron degenerate matter.
Is thalamic nuclei gray or white matter?
All of the cerebral cortex is gray matter as it composed of neuronal cell bodies which are not insulated with myelin.
Is the brainstem white matter or gray matter?
cortex is gray consisiting of neuron cell bodies.
What is white matter in the brain composed of?
largely or entirely composed of nerve fibers and contain few or no neuronal cell bodies or dendrites.
White matter of the nervous system is composed of?
White matter in the nervous system is caused when the axons in the area are myelinated. This means that the axons have a fatty protein covering to provide insulation. The myelin sheath is composed of special cells calls Schwann Cells.
