Question

multiple choice question
neurotransmitters are released by a neurons ______ into the synapse.

• bloodstream
• terminal button
• dendrites
• cell body

Explanation:

To solve this, we recall the structure and function of a neuron. Neurotransmitters are chemical messengers released from the terminal button (also called axon terminal) of a neuron into the synapse to transmit signals to other neurons. The bloodstream is not part of a neuron's structure for neurotransmitter release. Dendrites receive signals, and the cell body (soma) processes information but does not release neurotransmitters into the synapse.

Answer:

B. terminal button
