Which part of the neuron conducts the axon potential to the terminal buttons?

Question

BlackTom AI · Accepted Answer

The question asks which part of the neuron conducts the axon potential to the terminal buttons.
In typical neuronal structure, the axon is the long projection that transmits action potentials away from the cell body toward the synaptic terminals at the terminal buttons. The signal propagation along the axon is facilitated by the axon's membrane properties and, in myelinated fibers, by the myelin sheath with gaps called nodes of Ranvier that enable saltatory conduction.
Dendrites, by contrast, are primarily responsible for receiving incoming signals from other neurons and conveying them toward the soma. The soma (cell body) integrates inputs and organizes cellular maintenance, while the myelin sheath provides insulation and increases conduction speed but is not itself the conducting path for the action potential in the way the axon is. The terminal buttons are the synaptic endpoints where neurotransmitters are released, not the conduction pathway itself.
Because no answer choices were provided in the options list, we cannot evaluate each alternative line by line. However, understanding the functional roles described above clarifies that the axon is the component that propagates the action potential toward the terminal buttons, whereas dendrites, soma, and myelin play different roles in neural signaling.
