What is the primary function of the axon in a neuron?

The primary function of the axon in a neuron is to route messages to other neurons or muscles. An axon is a long, slender projection that transmits electrical impulses away from the neuron's cell body to communicate with other neurons or target tissues, such as muscles or glands. This is essential for the proper functioning of the nervous system, as it enables the rapid and efficient transmission of signals across distances.

In contrast, the other functions described in the other options do not accurately represent the role of the axon. For example, receiving incoming signals typically pertains to the role of dendrites, which are specialized structures that catch signals from other neurons. Supporting the structure of the neuron is primarily the role of the cell body and other neuron components, not the axon itself. Finally, concealing nerve impulses is not an accurate description of axonal function, as axons are designed to propagate, not hide, electrical signals necessary for communication within the nervous system.
