Psychopharmacology Final Exam with
100% fully solved questions(graded
A+)
Which method is dependent upon injecting a radioactive chemical into the blood to measure
glucose level? - answer PET scan
What do you come across first when you open up the skull? - answer Dura matter
Suppose a virus damaged only the dorsal roots of the spinal cord, but not the ventral roots. What
would happen to the sensory and motor abilities of the affected area? - answer Loss of sensation,
but preserved motor control
What is true about the myelin sheath? - answer -It is produced by glial cells
-Increases speed of signal conduction along axon
-Saves energy
NOT on all neurons
In a myelinated axon, where are action potentials regenerated? - answer at nodes of Ranvier
Neural transmission is generally within a single neuron and between neurons. - answer
electrical; chemical
Stimulus A depolarizes a neuron just above the threshold. Stimulus B depolarizes a neuron to 10 mV
beyond threshold. what can we expect to happen? - answer Stimulus A and B will produce the
same action potential response in the neurons
The term "hyperpolarization" refers to - answer movement of the resting membrane potential
farther from the threshold
, What is the most important consideration in developing a drug that will act in the brain? - answer
if the drug will cross the blood-brain barrier
Excitatory postsynaptic potentials are generally caused by channels opening, which inhibitory
postsynaptic potentials may be caused by channels opening - answer sodium, chloride
Ionotropic receptors - answer may depolarize OR hyperpolarize the postsynaptic membrane
The specific molecular changes that occur when a drug binds to a particular target site or receptor
is referred to as - answer drug action
What route of administration is most susceptible to the first-pass effect? - answer Oral
Drugs administered are absorbed the most rapidly - answer intravenously
In the dose-response curve, a decrease in potency is indicated by a shift to - answer the right
A dose-response curve shows that noncompetitve antagonists alter both the and the of
the antagonist, while competitive antagonists alter only the . - answer Potency, efficacy,
efficacy
-tolerance occurs as a result of cellular adaptation to the presence of a specific drug. -
answer Pharmacodynamic
Neurotransmitters are released into the while hormones are released into the . - answer
synapse; bloodstream
The primary treatment for Parkinsons's diseaseis the administration of L-DOPA because this drug -
answer is a precursor to dopamine
The first means of inactivation of the catecholamines is - answer reuptake by transportors
