Question

neurotransmitters are released by a neurons ______ into the synapse.

terminal button

cell body

bloodstream

dendrites

Explanation:

To solve this, we recall the structure and function of a neuron. Neurotransmitters are chemical messengers released into the synapse (the gap between neurons) from the axon terminal, also called the terminal button. The cell body (soma) is for maintaining the neuron, the bloodstream is not part of a neuron's structure for neurotransmitter release, and dendrites receive signals, not release neurotransmitters. So the correct option is terminal button.

Answer:

A. terminal button
