Question

True or False: Myelinated nerve fibers (axons) in the PNS are enveloped in Schwann cells.

Answer 1

True. Myelinated nerve fibers (axons) in the peripheral nervous system (PNS) are indeed enveloped in Schwann cells. These cells wrap around the axons, forming the myelin sheath that insulates them and helps to speed up the transmission of electrical signals.
