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?
Childhood experiences affect the rate of myelination in a child's brain. Myelination is the development of fatty sheaths around neurons, which help neurons communicate better and facilitates learning.
What is terminal zones of myelination?
Terminal zones of myelination refer to specific areas at the ends of myelinated axons where the myelin sheath terminates. These zones are important for the proper functioning of neurons, as they can influence signal transmission and the interaction between the axon and surrounding cells. They often contain specialized structures that facilitate communication, such as nodes of Ranvier, which are gaps in the myelin that allow for rapid conduction of electrical impulses. Understanding these zones is crucial for studying neurological diseases that affect myelination.
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.
How long does full myelination take?
Full myelination of the central nervous system typically occurs by early adulthood. However, the process can vary depending on the specific region of the brain and individual factors.
A process called myelination increases how fast you process information?
True
What does terminal zones of myelination result on MRI in a child indicate?
Terminal zones of myelination on MRI in a child typically indicate the completion of myelination in specific brain regions, often reflecting normal developmental milestones. These zones can be seen as areas where myelin formation is nearing its final stages, which is expected in young children as their nervous systems mature. However, variations in myelination patterns may also raise considerations for developmental disorders or neurological conditions, and should be interpreted in the context of the child's overall clinical picture.
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
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
