Nerve vs. Neuron — What's the Difference?
By Tayyaba Rehman — Updated on October 5, 2023
A nerve is a bundle of fibers transmitting impulses of sensation to the brain or spinal cord, and from these to the muscles and organs. A neuron is an individual nerve cell responsible for transmitting those impulses.

Key Differences
The human nervous system is a marvelously complex and intricate system. Within this system, both the terms "Nerve" and "Neuron" play vital roles, but they are distinct entities.
A nerve is essentially a cable-like structure in the body. It comprises multiple nerve fibers, or axons, that are encased in a protective sheath. These nerves are the highways for information, carrying signals between the brain and the rest of the body, making actions and perceptions possible. Without nerves, our brain wouldn't be able to communicate with our limbs, organs, or other body parts.
On the other hand, a neuron is the fundamental unit of the nervous system. It's an individual cell that can receive, process, and transmit information through electrical and chemical signals. These neurons are the building blocks of the brain, spinal cord, and nerves. Their structure consists of a cell body, dendrites, and an axon.
Furthermore, nerves are made up of many structures, including neurons. But not all parts of a nerve are neurons. In addition to neurons, nerves contain supportive cells and connective tissues. Meanwhile, a neuron is an independent entity with a specific structure and function in the nervous system.
Lastly, while nerves act as the communication lines of the body, connecting various parts to the central nervous system, neurons perform the task of transmitting and processing information. Without neurons, nerves wouldn't have any information to carry.
