Question

______ is the process by which nerve cells are coated with far cells that enhances the speed and efficiency of the information traveling through the nervous system. (Remember to type only one word in the blank.)

Answer 1

Answer:

Myelination

Explanation:

The covering of myelin around the axons is called the myelin sheath. This myelin sheath helps in transfer of information faster and also in complex  processes of the brain. The process of myelination begins in the PNS (peripheral nervous system).

The myelinated section are seperated from each other with a gap called nodes of ranvier. Glial cells (oligodendrocytes) forms the myelin sheath in the central nervous system and schwann cells (glial cells) forms the myelin sheath in peripheral nervous system. The propagation of electrical impulse in the myelinated fibers is by saltatory conduction that is from one node to another.

Answer 2

Answer:

Myelination

Explanation:

Myelination refers to the process which forms a protective layer made up of lipid-containing substance fats around the neurons. This protective layer around the neuron is known as the myelin sheath.

The myelin sheath is formed by the Schwann cells in the peripheral nervous system by the extension and helical wrapping of the plasma membrane of the Schwann cells around neurons. similarly, Oligodendrocytes form the myelin layer around the neurons in the CNS.

Thus, myelination is the correct answer.
