Verified step by step guidance1
Understand the structure of a neuron: Neurons are the basic units of the nervous system and consist of a cell body, dendrites, and an axon.
Dendrites are tree-like structures that receive signals from other neurons and convey this information to the cell body.
Axons are long, slender projections that transmit signals away from the neuron's cell body to other neurons, muscles, or glands.
Each neuron typically has one axon, which can branch out to communicate with multiple target cells, but it does not have multiple axons.
Review the statements: Dendrites do not branch off axons; axons do not receive signals; interneurons are primarily in the central nervous system. Therefore, the correct statement is that a neuron only has a single axon.
