What is a bundle of neurons called?

Explanation:
Bundles of neurons are called nerves. In the peripheral nervous system, many neurons’ axons are wrapped together with connective tissue to form a nerve, which carries signals to and from the brain and spinal cord. An individual neuron is a single nerve cell, not a bundle. Dendrites are the branched parts that receive signals, while the axon conducts signals away from the neuron. So the term for a collection of neurons’ fibers in the periphery is nerves (in the central nervous system, similar bundles are called tracts).
