Answers-Latest Update.
True or False: A drug that can block transmitter binding to a receptor can lead to an
increase in the receptors activation. - Correct Answer False
It would decrease the receptors activation since the transmitter wouldn't be able to
innervate and activation the receptor while it is being blocked.
What is the definition of Neuropharmacology? - Correct Answer The study of drugs that
alter processes controlled by the nervous system.
What are some neuropharmacologic drug uses? - Correct Answer Depression, epilepsy,
HTN, asthma
They work to either excite or suppress neuronal activity.
What are some examples of processes that neuropharmacologic drugs can modify? -
Correct Answer Skeletal muscle contraction, cardiac output, vascular tone, respiration,
gastrointestinal function, uterine motility, glandular secretion, ideation, mood, and
perception of pain.
What sites of action can neuropharmacology use to regulate neuron physiology? - Correct
Answer Axonal conduction
Synaptic Transmission
Receptors
Are drugs that affect axonal conduction selective? Why or why not? - Correct Answer No,
they are not because drugs here will affect all nerve conduction that they have access to.
Are drugs that affect synaptic transmission selective? Why or why not? - Correct Answer
Yes, they are because synaptic regions vary cell to cell and employ different
neurotransmitters.
Arrange the steps of synaptic transmission in order from first to last occurrence.
A. Transmitter Storage
,B. Receptor Binding
C. Transmitter Release
D. Transmitter Synthesis
E. Termination of Transmitter - Correct Answer DACBE
If a drug increased the synthesis of a transmitter, would it increase or decrease the
receptor activation? - Correct Answer Increase
If a drug decreased the synthesis of a transmitter, would it increase or decrease the
receptor activation? - Correct Answer Decrease
If a drug synthesized a "super" transmitter, would it increase or decrease the receptor
activation? - Correct Answer Increase
If a drug reduced the storage of a transmitter, would it increase or decrease the receptor
activation? - Correct Answer Decrease
If a drug promoted the release of a transmitter, would it increase or decrease the receptor
activation? - Correct Answer Increase
If a drug inhibited the release of a transmitter, would it increase or decrease the receptor
activation? - Correct Answer Decrease
If a drug made a transmitter who was binding to a receptor have direct receptor activation,
would it increase or decrease the receptor activation? - Correct Answer Increase
If a drug enhanced the receptors response to the transmitter, would it increase or
decrease the receptor activation? - Correct Answer Increase
If a drug blocked the transmitters ability to bind to a receptor, would it increase or
decrease the receptors activation? - Correct Answer Decrease
If a drug blocked the reuptake of a transmitter into a cell for termination, would it increase
or decrease the receptors activation? - Correct Answer Increase
,If a drug inhibited the breakdown of a transmitter, would it increase or decrease the
receptors activation? - Correct Answer Increase
True or False: High selectivity of a drug can alter a disease process while leaving other
physiologic processes largely unaffected. - Correct Answer True
In the example about opposing effects of nerves on the heart, which system slows the
heart rate?
A. Somatic Motor
B. Parasympathetic
C. Sympathetic - Correct Answer B
Acetylcholine, released from parasympathetic post-ganglionic neurons, interacts with
which receptor type on organs?
A. Nicotinic-N
B. Alpha-1
C. Muscarinic
D. Beta-2
E. Nicotinic-M - Correct Answer C
Which cholinergic or adrenergic receptor subtype is located presynaptically rather than
postsynaptically in the periphery?
A. Beta-1
B. Nicotinic-N
C. Muscarinic
D. Alpha-2
E. Nicotinic-M
F. Dopamine - Correct Answer D
Which neurotransmitter is enzymatically broken down in the synapse?
, A. Epinephrine
B. Acetylcholine
C. Norepinephrine - Correct Answer B
What are the two main divisions of the Nervous System? - Correct Answer Central and
Peripheral Nervous Systems
What are the two components of the CNS? - Correct Answer Brain and Spinal Cord
What are the two divisions of the PNS? - Correct Answer Autonomic and Somatic Motor
Systems
What are the two divisions of the Autonomic Nervous System? - Correct Answer
Parasympathetic and Sympathetic Nervous Systems
What are the functions of the Autonomic Nervous System? - Correct Answer Regulates
the heart, regulates the secretory glands (salivary, gastric, sweat, bronchial), regulates
the smooth muscles (bronchi, blood vessels, urogenital system, gastrointestinal tract)
Are the functions of the Autonomic Nervous System shared by both divisions? - Correct
Answer Yes
What are the 7 regulatory functions of the Parasympathetic Nervous System? - Correct
Answer "Housekeeping chores" of the body
Slows the heart rate
Increases gastric secretions
Empties the bladder
Empties the bowel
Focuses eyes for near vision
Constricts pupil of the eyes
Contracts bronchial smooth muscle
