Bundles of axons in the peripheral nervous system are known as what?

Explanation:
Bundles of axons in the peripheral nervous system are nerves. A neuron is a single nerve cell, and an axon is one long projection from that cell. A synapse is the junction where communication occurs between neurons. In the PNS, many axons are wrapped together in a nerve, surrounded by connective tissue and blood vessels, which allows both sensory and motor signals to travel along that cable. If you were talking about the CNS, the similar bundle of axons is called a tract, not a nerve.
