Question

Quizplus · Accepted Answer

Unmyelinated axons rest in invaginations of Schwann cells or oligodendrocytes. Myelinated axons have a myelin sheath around them which is produced by Schwann cells in the peripheral nervous system and oligodendrocytes in the central nervous system. The myelin sheath acts as an insulator, increasing the speed of conduction of action potentials by allowing electrical charges to jump between nodes of Ranvier.
