Which part of a neuron sends information away from the cell body?

• A. Axon
• B. Dendrites
• C. Nucleus
• D. Cell body

Answer: (A)

Information travels away from the cell body along the axon. The axon is specialized to carry electrical impulses, the action potentials, from the soma toward the synaptic terminals where signals are released to the next cell. Dendrites, in contrast, are the receiving branches that collect information from other neurons. The nucleus inside the cell body contains genetic material and helps regulate cell functions, but it doesn’t send signals away. The cell body itself supports the neuron’s metabolism and integrates inputs, but the actual long-distance signal transmission outward is done by the axon.
