Frequently Asked Questions

What are neurons and how do they work?

In this article, we explain what neurons are and how they work. In short, our nervous systems detect what is going on around us and inside of us; they decide how we should act, alter the state of internal organs (heart rate changes, for instance), and allows us to think about and remember what is going on.

What is the shape and size of a neuron?

A neuron varies in shape and size depending on its function and location. All neurons have three different parts – dendrites, cell body and axon. These are branch-like structures that receive messages from other neurons and allow the transmission of messages to the cell body.

What is the difference between a nerve cell and a neuron?

Alternative Titles: nerve cell, neurone. Neuron, also called nerve cell, basic cell of the nervous system in vertebrates and most invertebrates from the level of the cnidarians (e.g., corals, jellyfish) upward. A typical neuron has a cell body containing a nucleus and two or more long fibres.

What are the parts of a neuron?

Most neurons have a cell body, an axon, and dendrites. The cell body contains the nucleus and cytoplasm. The axon extends from the cell body and often gives rise to many smaller branches before ending at nerve terminals. Dendrites extend from the neuron cell body and receive messages from other neurons.
