It insulates the axon of the neuron?
An insulating layer that surrounds the axon is a myelin sheath.
What part of the nervous system is affected by poliomyelitis?
The myelin sheath surrounding nerves.
Are Schwann cells found in the central nervous system?
myelin sheath
What forms myelin sheath?
The glial cells: oligodendrocytes for central nervous system and schwann cells for peripheral nervous system.
How does a myelin sheath form?
The myelin sheath is an extruded plasma membrane wrapped in a spiral fashion around a nerve axon. The myelin membranes are part of the Schwann cells of the peripheral nervous system.
What type of cells produce the myelin sheath in the central nervous system?
Oligodendrocytes and Schwann cells both produce myelin. Oligodendrocytes produce myelin in the CNS, whereas Schwann cells produce myelin in the PNS. CNS refers to central nervous system PNS refers to peripheral nervous system
What is axonal substance called?
Myelin is a fatty sheath around axons found in the peripheral nervous system.
Do neurotransmitters form the myelin sheath?
No, not at all. The myelin sheaths are actually made by other living cells in the nervous system known as glia. Two types of glia myelinate the nervous system: oligodendrocytes and Schwann cells. The oligodendrocytes for myelin in the central nervous system (brain and spinal cord) and the Schwann cells form myelin in the peripheral nervous system (everything outside the brain and spinal cord).
The role of the myelin sheath?
it I a receptor so it gets a message then send that message to the CNS (central Nervous System)
What are the Ascending pathways of the central nervous system composed of?
The Ascending pathways of the central nervous system is made of "White Matter." (Vast amount of Axons coated with a sheath of Myelin)
What cells make up the mylin sheath?
There are two cells that are involved in the myelin sheath. One type is found in the central nervous system (CNS) and the other is in the peripheral nervous system (PNS).These are the oligodendrocytes (CNS) and Schwann cells (PNS).
Are muscles and glands myelinated?
Muscles and glands are not myelinated. It is the axon of a neuron that is myelinated. The myelin forms a layer called myelin sheath that makes the nervous system function properly.
