Nerve cells are covered with connective tissue. So that current does not flow from one cell to other by short circuit. This is very important for the integrity of the nervous system. This is just like insulation of electric wires. So if the wires are not insulated you will get the gadgets short circuited.

What facilitates the rate of myelination?
The rate of myelination is facilitated by several factors. One important factor is the activity of oligodendrocytes, the cells responsible for producing myelin in the CNS. Another factor is the presence of axonal signals that trigger oligodendrocyte differentiation and myelination. Additionally, the level of neuronal activity and electrical impulses can also influence the rate of myelination.
What are swan cells?
Responsible for myelination of neurons.
In what part of the brain does myelination occur last?
forebrain
What does gray matter lack that white matter has?
Myelination
What structure is responsible for myelination of the nerve fibers?
In the peripheral nervous system the cell that myelinates an axon is called a Schwann cell. In the central nervous system myelination is carried out by oligodendrocytes.
A factor that determines the rate of impulse propagation or conduction velocity along an axon?
The speed at which neural impulses are transmitted. Diameter of the axon Degree of myelination of the axon
A process called myelination increases how fast you process information?
True
Does the the autonomic nervous system typically have thin fibers with little or no myelination?
yes.
Is myelination of the nerve fibers in the Central Nervous System the job of the oligodendrocyte?
True
What is the process by which individual axons are insulated with fatty sheaths to enhance efficiency?
Myelination is that process.
Which two characteristics of axons increases the speed of nerve impulse?
diameter and presence of myelination.....
What are oligodendrocytes responsible for?
myelination of the axons and the dendrites are responsible for connection between the cell body and myelin
