What is the role of an axon in a neuron?

The role of an axon in a neuron is primarily to transmit signals between neurons. This long, slender projection of a neuron is essential for communicating information throughout the nervous system. Axons conduct electrical impulses away from the neuron's cell body and towards other neurons, muscles, or glands, allowing for the transmission of information in the form of action potentials.

Axons are covered by a myelin sheath, which increases the speed of signal transmission, facilitating swift communication across long distances in the body. This ability to relay messages is crucial for coordinating actions, processing information, and maintaining bodily functions. The prominence of axonal transmission is a key feature in the network of neural communication, making it distinct from the other options which pertain to other functions or components of neurons.
