Neurons facilitate nerve signaling with components like axons and synapses. Which component is responsible for transmitting signals away from the cell body?

The component responsible for transmitting signals away from the cell body is the axon. Axons are long, slender projections of a neuron that carry electrical impulses, known as action potentials, away from the neuron's cell body toward other neurons, muscles, or glands. This is a critical function in the nervous system, as it allows for the communication between different parts of the body and the brain.

Dendrites, on the other hand, are structures that receive signals from other neurons and transmit them toward the cell body, playing a key role in bringing information into a neuron rather than sending it out. Myelin is a fatty substance that insulates axons and enhances the speed of electrical signal transmission, but it does not actively transmit signals itself. Synapses are the junctions between neurons where the transmission of signals occurs but are not responsible for the actual outgoing propagation from the cell body. Thus, the axon is the correct choice for the component that facilitates the transmission of signals away from the neuron.
