What forms myelin sheath?
The glial cells: oligodendrocytes for central nervous system and schwann cells for peripheral nervous system.
Why can the peripheral nervous system heal but the central nervous system can't?
the schwann cells (supportive cells) in the peripheral nervous system allow the neurons to regenerate, while the supportive cells in the central nervous system (oligodendrocytes and astrocytes) prevent neuron regeneration.
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
Which type of glial cells produces the myelin sheaths that insulate axons or nerve fibers in the central nervous system (CNS)?
myelin sheath
Which type of neuroglial cells help to produce and circulate cerebrospinal fluid?
Ependymal cells of the Central Nervous system
Schwann cells are a type of ___ of the peripheral nervous system?
glial cells
What type of tissue Contains schwann cells?
Schwann cells are glia that myelinate the neurons of the Peripheral Nervous System
Myelin is formed by?
there are specialized cells in the nervous system produce and form the myelin in the central nervous system (brain & spinal cord) by oligodendrocytes in the peripheral nervous system by schwann cells
Do neurotransmitters form the myelin sheath?
No, neurotransmitters do not form the myelin sheath. Myelin is formed by specialized types of glial cells called oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. Neurotransmitters are chemicals that are released by neurons to transmit signals across synapses.
Specialized cells that myelinate the fibers of neurons found in the pns?
Peripheral Nervous System= Oligodendrites Central Nervous System= Schwaan Cells Oligodendrites myelinate 250 times faster than Schwaan cells
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).
Where are schwann cells found?
In the peripheral nervous system otherwise known as the PNS.
