Question

The axons of certain neurons are covered by a layer of fatty tissue that helps speed neural transmission. This tissue is

Answer 1

Answer:

Myelin sheath

Explanation:

Myelin sheath cover the axon of neurons and act as insulator for the faster transmission of signals.

Each axon is covered by multiple myelin sheaths and the gap between myelin sheath are known as Nodes of Ranvier.

In CNS myelin sheath is composed of glial cell called as oligodendrocytes and in PNS the myelin sheath is composed of Sachwann cells (glial cells).
