Functional Anatomy of Peripheral Nerves: Diagnostic and Therapeutic Advances

Kenji Sato

The peripheral nervous system serves as the essential communication network between the central nervous system and the rest of the body, transmitting sensory information, coordinating motor function and regulating autonomic activities. Peripheral nerves are highly organized anatomical structures composed of axons, Schwann cells, connective tissue layers and an extensive vascular supply, all of which contribute to their functional integrity. Advances in anatomy, neurophysiology, imaging and regenerative medicine have significantly improved our understanding of peripheral nerve function and pathology. These developments have transformed both the diagnosis and treatment of peripheral nerve disorders, offering new opportunities to restore function and improve patient outcomes. Functional anatomy provides the foundation for understanding peripheral nerve physiology. Each peripheral nerve contains bundles of myelinated and unmyelinated fibers enclosed by the endoneurium, perineurium and epineurium, which provide mechanical protection while maintaining the internal assessment. evaluation remains an indispensable component of peripheral nerve Nerve conduction studies and electromyography provide objective measurements of nerve function by evaluating conduction velocity, signal amplitude and muscle activation patterns. When combined with advanced imaging, these techniques offer complementary information that improves diagnostic accuracy and distinguishes between axonal injury, demyelination and neuromuscular disorders. This integrated approach has become particularly valuable in the diagnosis of entrapment neuropathies, diabetic neuropathy, inflammatory neuropathies and traumatic nerve injuries. microenvironment required for efficient
