What is myelinated?

Answer 1

Myelinated usually refers to the axon of a nerve cell. Myelin is a phospholipid sheath that surrounds the nerve cell's axon. By doing this, the axon- which is the long part of the nerve cell that can stretch throughout your body, is able to transmit electrical signals at a quicker pace. The myelin is interrupted every several nanometers by a space called a node, transmitting from node to node is easier than transmitting down the entire length of the nerve. To give you an example of its importance, if your myelin sheaths degrade, you end up with something like multiple sclerosis- the myelin no longer keeps the electrical signal along its intended nerve and you get uncontrolled movements.

Answer 2

Myelin is the sheath covering the neurons. Myelinated means covered, sheathed neurons. Demyelination and subsequent scarring to sclerosis and when it happens at many places in many nerves, it is called Multiple Sclerosis (MS).

I am not sure whether this is correct in the context of your question.

Answer 3

Some nerves are covered with another insulating cell that forms a thick layer around the nerve cell axon. Those are myelinated nerves.

Answer 4

myelinated is similar to insulated! a mylineated sheath of a neuron is kinda the same as an insulated electrical wire. it surrounds the neuron, preventing the electrical discharge from escaping as it passes through the neuron.
