Which part of the neuron carries nerve impulses away from the cell body?

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

Answer: (C)

The axon is the part of the neuron responsible for transmitting nerve impulses away from the cell body. It serves as a long, slender projection that conducts electrical signals, known as action potentials, to other neurons, muscles, or glands. The primary function of the axon is to ensure that the signals generated in the neuron are efficiently relayed to other parts of the nervous system. Dendrites are responsible for receiving incoming signals from other neurons and conducting these inputs toward the cell body, but they do not carry impulses away. Synapses are the junctions where communication occurs between neurons, transmitting signals but not carrying impulses away. The cell body contains the nucleus and is where the neuron's metabolic activities take place, but it is not responsible for the transmission of impulses away from itself. Thus, the axon's primary role in propagating nerve impulses makes it the correct choice for this question.
