Myelinated axons

Myelinated axons are nerve fibers surrounded by a protective, insulating layer called myelin. This insulation, made of fatty substances, helps electrical signals travel faster along the nerve. Think of it like the plastic covering on electrical wires, which keeps the signals strong and prevents interference. Myelinated axons are essential for quick communication between the brain, spinal cord, and other parts of the body, enabling rapid responses like reflexes and coordinated movements. This efficient transmission is critical for proper nervous system function and overall body coordination.
