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 happens if the myelin sheath is damaged?
Two things, 1, the conduction speed of the neuron will be reduced. 2, the neuron will be subject to 'activation' from extraneous sources.
What state of matter is the mind?
The mind is not any state of matter.The mind is an epiphenomenon of the electrobiochemistry happening in the unbelievably complicated network of neurons, myelin, neurotransmitters, neuromodulators, neuroregulators, hormones, etc. that make up the about three pounds of largely fatty tissue enclosed in our bony skull that we refer to as a brain.
Explain how neurotransmitters affect behavior?
Neurotransmitters can directly or indirectly affect behavior. It influences neurons in a specific portion of the brain. Any abnormal level in neurotransmitters can lead to mental disorders.
Why would a psychologist pay attention to neurotransmitters?
Because neurotransmitters can affect behavior and cognitive abilities. See the related link for a good discussion.Because neurotransmitters can affect behavior and cognitive abilities.

In a typical neuron sheaths of fatty tissue are called?
In a typical neuron, sheaths of fatty tissue are called the Myelin sheath. The myelin sheath surrounds parts of the axon of a nerve cell which speeds up neurotransmitters.
What is the fatty tissue that covers axons and speeds up impulses as they travel from cell to cell?
That substance is called the myelin cell or myelin sheath.
What increases the speed of the transmission?
Myelin Sheath Myelin Sheath
The Schwann cell forms a myelin sheath around the?
axon of a neuron in the peripheral nervous system.Schwann cells form a myelin sheath around the Axon.
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 are schwann cell nucleus'?

What increases the speed of impulse transmission?
Myelin Sheath Myelin Sheath
It insulates the axon of the neuron?
An insulating layer that surrounds the axon is a myelin sheath.
The layer of lipid around an axon is called?
Myelin sheath
What is myelin sheath on nerve fibers?
The endoneurium surrounds and protects the myelin sheath.
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.
What creates myelin sheath?
Oligodendrocytes are specialized neurolgical cells that produce myelin sheath.
