Nerves are defined as thick bundles of axons that form the primary structure of the Peripheral Nervous System. They function as two-way superhighways for communication, containing thousands of both efferent (motor) and afferent (sensory) axons to carry messages back and forth between the Central Nervous System and the body's muscles, organs, and sensory systems.

The Peripheral Nervous System (PNS) is a major division of the nervous system consisting of nerves located in the periphery of the body, which includes everything outside the central nervous system (CNS). These thick bundles of axons carry messages back and forth between the CNS and the body's muscles, organs, and senses.

The main pathway through the body that controls movement and recieves sensory information. There are two anatomical groups of nerves that are part of the system - cranial nerves and spinal nerves.
