Answer to Question 1

Ans: D
Feedback:
The mesolimbic pathway is thought to be involved in pleasurable sensations and euphoria resulting from substance abuse. Deficiencies in the nigrostriatal pathway result in movement disorders (eg, Parkinson's disease) and contribute to certain side effects of antipsychotic medications. The mesocortical pathway is thought to mediate both the negative and cognitive symptoms of psychosis. The tuberoinfundibular pathway regulates prolactin secretion.

Answer to Question 2

Ans: D
Feedback:
Neurotransmitters are referred to as first messengers, which refers to molecules that communicate information or change from one cell or cell group to another, cause an immediate effect, and are typically found in circuitry that produces behavior. Glial cells are not involved in neurotransmission and receptor cells do not lie within the synapse.
