Bundles of axons that form neural cables connecting the CNS to the rest of the body.

Nerves are bundles of axons that connect the central nervous system to the rest of the body. These axon bundles are wrapped in connective tissue and form the pathways that carry sensory information to the brain and motor commands from the brain to muscles, spanning the peripheral nervous system as cranial and spinal nerves. In the central nervous system, the same idea exists but the bundles are called tracts rather than nerves. Interneurons are individual neurons that operate within the CNS to connect other neurons; neurons are the basic nerve cells themselves; synapses are the junctions where neurons communicate.
