The gap into which the neurotransmitters are released is the
A)receptor field.

C)axon terminal.
D)synaptic cleft.

Question

Quizplus · Accepted Answer

The gap into which neurotransmitters are released is called the synaptic cleft. This is the narrow space between the presynaptic neuron's axon terminal and the postsynaptic neuron's dendritic spine or cell body, where the neurotransmitters are released and bind to their receptors. Choice A (receptor field), while a term related to the effect of neurotransmitters on target cells, does not specifically refer to the gap between neurons. Choice B (dendritic branch) is a part of the postsynaptic neuron that receives the neurotransmitters, but it is not the gap into which they are released. Choice C (axon terminal) is the site of neurotransmitter release but it does not describe the gap itself.
