What term describes the end-plates of the axon that usually have a synapse to pass on the signal?

• A. Dendrite
• B. Synapse
• C. Myelin sheath
• D. Axon terminal buds

Answer: (D)

Signal transmission between neurons happens at the ends of an axon where it forms a synapse. These ending parts are the axon terminals, often described as terminal buds. They house vesicles with neurotransmitters and release them into the synaptic cleft when an action potential arrives, so the signal can be passed to the next cell. Dendrites receive signals, not send them; a synapse is the junction itself, not the end part; and the myelin sheath insulates the axon. So the end-plates of the axon that pass on the signal are the axon terminal buds.
