A(n)_______________ is a presynaptic receptor that is activated by neurotransmitters different from those released from the axon terminal.
A) heteroceptor
B) autoreceptor
C) postsynaptic receptor
D) axon terminal receptor

Question

Quizplus · Accepted Answer

A heteroceptor is a presynaptic receptor that responds to neurotransmitters other than those released from the axon terminal. Autoreceptors, on the other hand, are presynaptic receptors that respond to the same neurotransmitter that is released from the axon terminal. Postsynaptic receptors are located on the surface of the postsynaptic neuron and respond to the neurotransmitter released from the presynaptic neuron. Axon terminal receptors are not a known type of presynaptic receptor.
