Where are myelin sheaths located?
Myelin sheaths are located around the nerve cells. In central as well as peripheral nervous system.
What are progressive destruction of myelin sheaths in the central nervous system is called?
MS
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.
Does oligodendrocytes serve the same purpose in the central nervous and periphial nervous system?
No, they form myelin sheaths on axons in the CNS while schwann cells form myelin sheaths in the PNS. Hope this answers your question.
Which neuroglial cell is responsible for the production of myelin sheaths around axons in the central nervous system?
Oligodendrocyte; processes of the oligodendrocytes form the myelin sheaths around the CNS nerve fibers
How do nerve axons enhance speed of nerve impulse transmission?
By being wrapped in myelin sheaths, produced by Schawann cells in the peripheral nervous system and oligodendrocytes in the central nervous system.
What insulates nerve fibers?
Myelin sheaths insulate nerve fibers
The brain and the spinal cord together make up what is known as the?
The brain and spinal cord are the two components of the Central Nervous System, and the CNS is composed of mostly neurons, with oligodendrocytes to provide myelin sheaths, microglia as immune cells, and astrocytes for general support. Other cell types (ependymal cells, radial glia) also exist in isolated locations.
What does ALD do to the white matter in the brain?
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.
Does a nervous breakdown affect the myelin sheaths?
No. It does not. It can not. It neither affect the neurons also.
What types of nervous cells are in the spinal nodes?
The perikaryon (cell body) is the neuron central part, to other neurons or directly to muscles or glands. These sheaths are composed of cell membranes from Schwann cells.
What PNS neuroglia help to form myelin sheaths around larger nerve fibers in the PNS?
In the peripheral nervous system, Schwann cells are responsible for forming myelin sheaths around the larger nerve fibres in the PNS. Keep in mind that one Schwann cell myelinates one nerve. You may hear about oligodendrocytes, but these are responsible for myelination in the Central Nervous System, and myelinate multiple nerves.
