A client with a diagnosis of depression has been prescribed a medication that ultimately increases the levels of the neurotransmitter serotonin between neurons
Which of the following processes will accompany the actions of the neurotransmitter in a chemical synapse?
A)
Two-way communication between neurons is permitted in contrast to the one-way communication in electrical synapses.
B)
Communication between a neuron and the single neuron it is connected with will be facilitated.
C)
The neurotransmitter will cross gap junctions more readily.
D)
More neurotransmitters will cross the synaptic cleft and bond with postsynaptic receptors.
Ans:
D
Feedback:
In chemical synapses, neurotransmitters cross the synaptic cleft and bond with postsynaptic receptors to facilitate communication between neurons. This communication is one way, not two way, and each neuron has synaptic connections with thousands of other neurons. Gap junctions are associated with electrical synapses, not chemical synapses.
