How is myelin formed within the central nervous system?
The glial cells that surround the neurons produce myelin.
Formed by schwann cells in the PNS?
Myelin sheath
The myelin sheath that covers many CNS axons is formed by?
Oligodendrocytes
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 insulates nerve fibers?
Myelin sheaths insulate nerve fibers
What is the definition of myelin sheath?
A myelin sheath is a layer of myelin (a dielectric, or electric insulator) around the axon of a neuron.
It insulates the axon of the neuron?
An insulating layer that surrounds the axon is a myelin sheath.
What increases the speed of the transmission?
Myelin Sheath Myelin Sheath
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.

What increases the speed of impulse transmission?

How does nicotine affect the myelin production?
Nicotine stimulates CREB phosphorylation which regulates the expression of myelin basic protein and myelin oligodendrocyte glycoprotein.
