Answer to Question 1

Ans: B
The synaptic cleft, a junction between one nerve and another, is the space where the electrical intracellular signal becomes a chemical intracellular signal. The soma is the neuron's cell body. A terminal is the end of an axon. A receptor site is the area of the postsynaptic membrane that accepts the released neurotransmitter.

Answer to Question 2

Ans: D
Schizophrenia is associated with abnormally high activity of dopamine, not serotonin. Therefore, the students would need additional review. Whereas depression and insomnia have been associated with decreased levels of 5-HT, mania has been associated with increased 5-HT. Some of the most well-known antidepressant medications, such as fluoxetine and sertraline, function by increasing serotonin concentrations within certain areas of the central nervous system..
