Axons vs. Dendrites: What's the Difference?

Edited by Sara Rehman || By Sawaira Riaz || Published on December 8, 2023
Axons are long nerve fibers transmitting impulses away from the neuron's body, while dendrites are shorter, branched structures receiving signals to the neuron.

Key Differences

Axons are elongated fibers of neurons responsible for transmitting nerve impulses away from the neuron cell body. Dendrites, in contrast, are tree-like extensions of the neuron that receive signals from other neurons.

An axon typically has a uniform structure and can extend long distances from the neuron body, facilitating rapid signal transmission. However, dendrites are shorter, highly branched, and designed to maximize the surface area for receiving incoming signals.

The axon's primary function is to conduct electrical impulses, known as action potentials, to other neurons, muscles, or glands. Dendrites function primarily as the receivers of chemical signals from the synapses of other neurons.

In terms of anatomy, axons are often insulated by a myelin sheath, enhancing signal speed and efficiency. While, dendrites lack this myelination, focusing instead on receiving a broad range of synaptic inputs.

Axons end in terminal buttons that release neurotransmitters into synapses. Dendrites contain numerous receptor sites to which these neurotransmitters bind, initiating or inhibiting new action potentials.
