The gap between neurons where neurotransmitters are released is called what?

• A. Synapse
• B. Dendrite
• C. Synaptic cleft
• D. Axon terminal

Answer: (C)

The space between neurons where neurotransmitters are released is called the synaptic cleft. When an action potential reaches the presynaptic axon terminal, neurotransmitters are released into this narrow gap and diffuse across to bind receptors on the postsynaptic membrane, producing a response. The term synapse describes the entire junction between the two neurons and the cleft, not just the gap itself. The dendrite is the receiving surface of the postsynaptic neuron, while the axon terminal is the part of the presynaptic neuron that releases the neurotransmitters into the cleft.
