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).
What else can I help you with?
The role of the myelin sheath?
The myelin sheath is a protective covering that surrounds nerve fibers and helps in efficient transmission of nerve impulses. It acts as an insulator, speeding up the transmission of signals along the nerves. Damage to the myelin sheath can result in disruptions in nerve signal transmission and lead to conditions such as multiple sclerosis.
What happens if the myelin sheath is damaged?
If the myelin sheath is damaged, nerve signals may slow down or be disrupted, leading to problems with movement, sensation, and coordination. This can result in various neurological symptoms, such as weakness, numbness, and tingling. In severe cases, it can lead to conditions like multiple sclerosis.
What are the colors of your nervous system?
Nervous tissue does not have a specific color as it is made up of cells, fibers, and blood vessels. However, nerve tissue can appear white due to the myelin sheath that surrounds certain nerve fibers.
Action potentials trigger the release of chemicals in the terminal buttons called?
neurotransmitters. These neurotransmitters are released into the synaptic cleft to relay signals to the next neuron in the communication pathway.
Why would a psychologist pay attention to neurotransmitters?

Are neurotransmitters found in the myelin shealth?
No, neurotransmitters are not found in the myelin sheath. The myelin sheath is a protective covering that surrounds nerve fibers, while neurotransmitters are chemical messengers that transmit signals between neurons.
What does the schwann cell form a myelin sheath around?
Schwann cells form a myelin sheath around peripheral nerve fibers in the peripheral nervous system.

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.
What are axons surrounded by?
Axons are surrounded by myelin sheath, a fatty material that insulates and protects the axon. Additionally, axons are also surrounded by Schwann cells in the peripheral nervous system and oligodendrocytes in the central nervous system, which help form the myelin sheath.
What is the sheath of the Schwann Cell also called?
Surrounding the myelin sheath, there is a thin membrane called neurilemmal sheath. This is also called neurilemma or sheath of Schwann. This contains Schwann cells, which have flattened and elongated nuclei. The cytoplasm is thin and modified to form the thin sheath of neurilemma enclosing the myelin sheath. One nucleus is present in each internode of the axon. The nucleus is situated between myelin sheath adn neurilemma. At the node of Ranvier (where myelin sheath is absent), the neurilemma invaginates and runs up to axolemma in the form of a finger like process. In nonmyelinated nerve fiber, the neurilemma continuously surrounds axolemma. Neurilemma is absent in central nervous system. Neurilemma is necessary for the formation of myelin sheath (myelinogeneis).
What surrounds the axon?
The axon is surrounded by the myelin sheath, which is a fatty insulating layer that speeds up the transmission of electrical signals. Outside the myelin sheath, there are Schwann cells or oligodendrocytes (depending on the type of neuron) that help form and maintain the myelin sheath.
