Which structure transmits information to other neurons and to muscles and glands?

• A. Dendrite
• B. Soma
• C. Synapse
• D. Axon

Answer: (D)

Neural signals are sent along the axon, the long fiber that carries electrical impulses away from the neuron's body toward other neurons and toward muscles or glands. After the signal is generated in the dendrites and soma, it travels down the axon as an action potential. The axon terminals then release neurotransmitters at synapses to pass the message to the next cell. Dendrites and the soma mainly receive and integrate information rather than send it onward, and the synapse is the site of communication, not the carrying structure itself. Myelination along the axon speeds up this transmission. So, the structure that transmits information to other neurons and to muscles and glands is the axon.
