Answer:
Providing insulation
Supporting nerve regeneration
Step-by-step explanation:
Schwann cells are specialized cells that are found in the peripheral nervous system. Their main functions are:
Providing insulation: Schwann cells are responsible for producing a fatty substance called myelin, which surrounds and insulates nerve fibers. This insulation helps to increase the speed of nerve signal transmission and prevents electrical signals from leaking out of the nerve fibers.
Supporting nerve regeneration: When nerve fibers are damaged, Schwann cells play a critical role in facilitating their regeneration. Schwann cells produce growth factors and other molecules that promote the growth of new nerve fibers and help to guide them to their correct destinations. Additionally, Schwann cells can also form a type of scaffold that guides regenerating nerve fibers and provides them with a supportive environment to grow.
