Advanced Usage

• "axonal degeneration": The pathological process of breakdown or deterioration of an axon, often following injury or in certain diseases.
  • The disease is characterized by progressive axonal degeneration in the spinal cord.
• "axonal guidance": The process by which growing axons navigate to find their correct targets during nervous system development.
