The function of myelination in the nervous system is to allow neural impulses to travel longer distances in axons quickly; the process is as follows: helper cells (glia) wrap either themselves (in the case of Schwann cells), or parts of themselves (in the case of oligodendrocytes), all along the length of a myelinated axon, with gaps between each wrapping, kind of like shis-kabobs; the wrapping insulates the axon, preventing ion leakage, such that the membrane potential at one gap (called a node of Ranvier) can directly affect the voltage-gated sodium ion pores at the next gap, thus moving the neural impulse more quickly than if the action potential were happening in all of the intervening spaces beneath the myelin sheaths. The action potential is re-triggered at each node, thus maintaining the strength of the impulse from start to finish along the whole length of the axon, while the electrotonic conduction under the myelin sheath provides the speed necessary for effective nervous system processing over longer distances.
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.
they are two types of glia cells. oligodendrocytes are responsible for the myelination of neurons in the central nervous system. swan cells perform the same function but in the peripheral nervous system.
Myelination is the process by which a myelin sheath is formed around nerve fibers, allowing for faster and more efficient transmission of electrical signals within the nervous system. This sheath is produced by specialized cells called oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. Myelination plays a critical role in regulating nerve impulse conduction and promoting proper functioning of the nervous system.
The process is called myelination, where individual axons are wrapped in layers of fatty material called myelin produced by specialized cells called oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. Myelin acts as an insulating layer that helps speed up the transmission of electrical signals along the axon, enhancing the efficiency of neural communication.
The central nervous system involves primarily the brain and spinal cord. The function of the system is to process information gathered from the nerves in the body to carry out motor function, maintain bodily systems, etc.

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.

yes.
True
What is meant in layman's term the nervous system growth process of synaptogenis, myelination, and pruning and how it relates to healthy human development. I am trying to explain this process to middle school kids.

there are nervous
One function of the nervous system is to maintain the entire body.
The nervous system functions do not form thoughts but it could contribute to them. Arousal, which is a nervous system function, could lead to desire.
Yes it is true that excretion is one function of the digestive system. The nervous system is made up of the peripheral nervous system and central nervous system.
