The Process of Myelination: How Glial Cells Insulate Axons in the Nervous System
Myelination represents a critical adaptation in the nervous system, where glial cells wrap layers of membrane around axons to enhance signal transmission speed and efficiency, fundamentally supporting rapid neural communication. This image illustrates the myelination process in both schematic and microscopic views, showcasing how Schwann cells in the peripheral nervous system (PNS) and oligodendrocytes in the central nervous system (CNS) form insulating sheaths, with detailed labels highlighting key structures like the myelin sheath and node of Ranvier. Such insulation enables saltatory conduction, where action potentials jump between nodes, accelerating impulses up to 100 times faster than in unmyelinated fibers, essential for coordinated movements, sensory processing, and cognitive functions.
