A synapse that contains a presynaptic heteroreceptor would be classified as a(n) ________ synapse.

Question

Quizplus · Accepted Answer

Axoaxonic synapses involve communication between two axons, not a heteroreceptor. Dendrosomatic, axodendritic, and somasomatic synapses all involve communication between a dendrite and a soma, which also would not contain a heteroreceptor. The only option left is E, dendroaxonic, but there is no indication that the synapse in question involves communication between a dendrite and an axon. Therefore, A is the best choice, as heteroreceptors are located on the presynaptic axon and can regulate the release of neurotransmitters from another neuron's axon.
