Which cell produces the myelin sheath for neurons in the CNS?
Oligodendrocytes produce the myelin sheath for neurons in the CNS.
Schwann cells form the myelin sheath in the PNS.
That is a very good question. Gray matter is composed of cell bodies of neurons. Such cell bodies are also covered by myalin sheath. But the colour of myalin sheath is dominated by the color of nerve cell bodies. ( Without the myelin sheath, there will be short circuit.)
The cell that is insulated by a fatty layer is the myelin sheath. It is the fatty insulator around the neurons (nerve).
The schwann cell is the myelin sheath.
The Schwann Cell produces the myelin sheath and functions in repair and regeneration of damaged nerves
A fatty substance that is wrapped around the shaft of axons in the nervous system and whose function is to insulate neurons and speed up the neural impulse?
That substance is called the myelin cell or myelin sheath.
A myelin sheath wrapped around the axon of a neuron. Neurons consist of three parts: a cell body, dendrites, and an axon. The dendrites are responsible for receiving stimuli from other nearby neurons. The stimulus is transferred down the dendrites into the cell body. From the cell body, the stimulus will travel down the axon, which is a long extension of the neuron. Axons are surrounded by a myelin sheath, multi-layered covering made up of… Read More
A neuron is a nerve cell, so it has all the parts of an animal cell, plus some specialized parts: axon, dendrites, and perhaps a myelin sheath for insulation.
CNS: oligodendrocytes make the myelin, they cooperate in the formation of a myelin sheath along the axon, this is the process of myelination. Each oligodendrocyte produces segments of several axons. PNS: schwann cells make the myelin, each schwann cell can myelinate one segment of a single axon and they work together ot form the myelin sheath.
A substance known as a myelin sheath coats the axon of a neuron cell. This coating helps protect the electrical impulse as it travels the nerve.
A nerve cell with a myelin sheath. The sheath acts as an insulator of electrical conduction which is how the nerve cell conducts action potential. It conducts faster because the insulator prevents flow of ions right beside the channels that are being activated. So it 'skips' distance.
axon of a neuron in the peripheral nervous system.Schwann cells form a myelin sheath around the Axon.
A+ Students - myelin sheath A Schwann cell is a particular type of neuroglial cell, found only in the peripheral nervous system. Schwann cells produce the myelin sheath, which insulates the axons of bodily nerves, increasing the signal velocity.
myelin is not a cell but it is a sheath around nerves that conduct impulses to the nerves they cover. once the myelin sheath is gone, either because of damage or disease it is very hard to grow more, it almost never happens. The myelin is made from glial cells or schwan cells.
The Schwann cells are also known as a Myelin sheath.
The main parts of a neuron are the dendrites, the cell body, and the axon. The axon is covered by a myelin sheath, and has axon terminals at the end which allow it to communicate with the dendrites of other neurons.
These are the basic parts of the neuron 1. the Dendrites (the nerve endings) 2. the axon (the body) 3. the Soma (the cell body) the axon is covered by the myelin sheath and like any other cell it has the nucleus

The Myelin sheath
Cell body (also known as soma) axon myelin sheath (not present in all neurons) synapse (at the end where neurotransmitters are released to. Not really a part as it is not technically attached to the neuron) dendrites axon terminal
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.
axon dendrite cell body nucleus myelin sheath
One is the Myelin Sheath, the other I would assume is the Neurilemma.
Because this is tissue from the brain (CNS), it is an oligodendrocyte which wraps around axons of neurons in the CNS to form a fatty myelin sheath. If it were PNS axons in say spinal or cranial nerves, the answer would be be Schwann cells.
The tissue is in the form of a sheath and is called myelin.
Oligodendrocytes - specialized neuroglial cells that assist in production of the myelin sheath.

Axons are coated in a fatty substance called myelin - a "myelin sheath". It insulates and protects the cell body of neurones. The myelin doesn't completely coat the axon: there are small gaps between the myelin, called the nodes of Ranvier.
Yes. You are right. White matter of brain is mainly composed of myelin sheaths, which surround the axons and gray matter is composed of nerve cell bodies.
* synapse * axon * motor end plate * cell body * myelin sheath * dendrites
The myelin sheath. Due to its insulating properties, the myelin sheath prevents the movement of ions in nerve cells. Therefore nervous impulses will jump between the gaps in the myelin sheath (called the Nodes of Ranvier). This is a lot quicker than the conduction in non-myelinated nerve fibres which occurs by the movement of ions across each of the nerve cell membranes.
The myelin sheath protects the information passing from one side of the nerve cell to the other. It blocks out other signals that might interfere.
Scwhann cells, a type of glial cell, wrap their membranes around neuronal axons many times to form the myelin sheath. It is mostly composed of lipids (fats)
The formation of myelin sheath around the axon is called the myelinogenesis. In the peripheral nerve, the myelinogenesis starts at 4th month of intrauterine life. It is completed only in the second year after birth. Before myelinogeneis, Schwann cells of the neurilemma are very close to axolemma as in the case of unmyelinated nerve fiber. The membrane of the schwann cell is double layered. The schwann cells wrap up and rotate around the axis cylinder… Read More
Which cell forms the myelin sheaths that surround the axons of some of the neurons in the central nervous system?
Because the sheath is produced by several Schwann cells that arrange themselves end to end along the nerve fiber, each Schwann cell forms only one part of the tiny segment of the sheath.
Is a chronic inflammatory disease of the nervous system in which immune cells attack myelin sheat of the nerve cell axons?
are you asking 'what is the chronic inflammatory disease in which the immune system attacks the myelin sheath of nerve cell axions? if that is your question, the answer is Multiple Sclerosis.
Nerve cells or neurons are well suited to their job of transmitting impulses around the body: * Myelin sheath insulates and protects the axons, * Many mitaochondria to produce enough energy to allow the cells to transmit the signal, * Cytoplasmic extensions enable rapid distribution of impulses.
A disease that effects the myelin sheath is multiple sclerosis (MS). The function of the myelin sheath is to act as an insulator for the nerve cell. It's kind of like the rubber casing found on the outside of wires to protect the electron movement inside and allow us not to get shocked. MS causes the destruction of the myelin sheath which causes it to scar and harden and as a result we short circuit… Read More

A myelin sheath produced by either a oligodendrocyte in the central nervous system or a Schwann cell in the peripheral nervous system.
Between myelin segments surrounding the axon The axon of a neuron is the single long fibre which caries impulses away from the cell body. It is surrounded by a fatty layer, the myelin sheath, produced by Schwann cells arranged along the length of the axon. The gaps between the myelin sheath cells are called nodes of Ranvier. See http://en.wikipedia.org/wiki/Axon for more information and a diagram. easy answer between the myelin segments surrounding the axon b… Read More
What part of neuron releases neurotransmitter my choices are axon axon terminal dendrite myelin sheath or cell body?
The neurotransmitter is released from the axon terminal.
The myelin sheath acts as a covering on the axon of a neuron just as the covering on the cord you plug into an electrical socket. If it is damaged, the current can be "short circuited" and the neuron and the axon will not function. This sheath allows impulses to travel rapidly. MS is a disease where these sheaths are damaged.
The Oligodendrocyte (spelling might be slightly wrong) is the equivalent of the Schwann cell. Both of them create a myelin sheath around the axon of a neural cell, which provides electrical insulation.
The myelin insulating sheath speeds up signal propagation down the axon. It also acts like the covering on any electric cord. It only covers the axon and since it is made of fatty materials, it appears white. The cell and dendrites appear gray.
