Serotonin - CORRECT ANSWER-- inhibitory
- controls sleep, pain control, sex, food intake, temperature
y-aminobutyric acid (GABA) - CORRECT ANSWER-- Inhibitory
- modulates other neurotransmitters
- controls anxiety
histamine - CORRECT ANSWER-- neuromodulator
- controls alertness, gastric secretions, cardiac stimulation
________is a neurotransmitter that is believed to be in overabundance in certain areas of the
brain responsible for hallucinations. Antipsychotic medications are thought to reduce this
neurotransmitter activity in the brain. - CORRECT ANSWER-Dopamine
, Blockage of M1 receptors inhibits ___________, which is an important neurotransmitter
involved in memory and organ functioning. Anticholinergic side effects related to antipsychotic
medications include blurred vision, dry mouth, constipation, and urinary retention. - CORRECT
ANSWER-acetylcholine
Blockage of these receptors leads to a reduction in ____________, which brings about
vasodilation. Because of this effect, there is a drop in blood pressure. - CORRECT ANSWER-
norepinephrine
Blocking the ____________1 receptors leads to sedation and weight gain, although some
patients who are agitated can benefit from the sedation. - CORRECT ANSWER-histamine
__________ is an enzyme believed to break down the group of neurotransmitters known as
monoamines (norepinephrine, serotonin, dopamine, and epinephrine). These are believed to
work by exerting their action on this enzyme (not allowing the breakdown of the monoamines).
________ also degrade monoamine substances that enter the body from food. If _________
cannot break down the tyramine from these foods, tyramine may produce vasoconstriction,
elevated blood pressure, and may precipitate a hypertensive crisis. - CORRECT ANSWER-
Monoamine oxidase (MAO)
__________ is a neurotransmitter that has a relaxing effect. Benzodiazepines work to enhance
the effects of _____________ to help us feel more relaxed. Relaxation may be accompanied by
the side effects of sedation, ataxia, and anterograde amnesia (trouble forming new memories
after taking a dose). - CORRECT ANSWER-y-aminobutyric acid (GABA)
__________ is the "feel-good" neurotransmitter. It is believed to be a major role in depression.
SSRIs are aimed at increasing ___________. Stimulation of various __________ receptors may
result in inhibited orgasm, low libido, apathy, nausea, and vomiting. - CORRECT ANSWER-
serotonin
