The main difference between Nerve and Neuron: A nerve is a bundle of many nerve fibers that transmit signals. A neuron is a single cell that conducts electrical and chemical signals.
Nerve vs Neuron — Comparison Table
| Basis | Nerve | Neuron |
|---|---|---|
| Definition | Bundle of nerve fibers | Single nerve cell |
| Structure | Multiple axons bundled together | Single cell with dendrites and axon |
| Composition | Made of neurons and glial cells | Individual cell with nucleus |
| Visibility | Visible to naked eye | Visible only under microscope |
| Function | Transmit signals between organs and CNS | Conduct impulses within itself |
| Example | Optic nerve, spinal nerve | Sensory neuron, motor neuron |
Key Points
- A nerve is composed of many neurons bundled together
- Neurons are basic units of nervous system
- Nerves connect brain to body organs
- Neurons have cell body, dendrites, and axon
Frequently Asked Questions
What is the difference between a nerve and a neuron?
A neuron is a single nerve cell — the basic unit of the nervous system. A nerve is a bundle of many nerve fibres wrapped together in connective tissue, visible to the naked eye, whereas a single neuron is microscopic.
What are the main parts of a neuron?
A cell body containing the nucleus, short branching dendrites that receive signals, and a long axon that carries the impulse away to the next cell. The junction where one neuron passes a signal to another is called a synapse.
How does a signal travel along a neuron?
It travels as an electrical impulse along the axon. At the synapse the electrical signal causes chemical messengers to be released, and these cross the tiny gap to start a new impulse in the next neuron.
