UMKC Neurophysiology III Questions With Complete
Solutions
5-HT Correct Answer serotonin
AA NT found at excitatory synapses Correct Answer
aspartate, glutamate
AA NT found at inhibitory synapses Correct Answer glycine,
GABA
ACh receptor Correct Answer cholinergic
acts as a retrograde messenger to stimulate release of more
glutamate, which is why it's important in LTP Correct Answer
Ca+2
Biogenic amine derived from tryptophan Correct Answer
serotonin
Catecholamines are derived from ____________- Correct
Answer tyrosine
Catecholamines bind (ionotropic/metabotropic) receptors
Correct Answer metabotropic (adrenergic)
class of NTs that play essential roles in mood, consciousness,
motivation, directed attention, movement, blood pressure
regulation, hormone release Correct Answer catecholamines
, couples frequent activity across a synapse with long term
changes in the strength of signaling across the synapse; one of
the major cellular processes involved in learning and memory
Correct Answer LTP (long term potentiation)
decreases likelihood of post-synaptic neuron firing an AP
Correct Answer post-synaptic inhibition
drug type that increase the amount of NE and 5-HT in the pre-
synaptic nerve terminal Correct Answer MAO inhibitors
Electrical conduction is ______________ in nature, which
means that the graded potential loses strength as it moves across
the cell body (local current flow) Correct Answer decremental
enzyme that degrades ACh Correct Answer
acetylcholinesterase (AChE)
enzyme that degrades catecholamines; lots of anti-depressent
drugs inhibit this Correct Answer MAO (monoamine oxidase)
enzyme that synthesizes ACh from acetyl coA and choline
Correct Answer CAT (choline acetyl transferase)
examples of purine NT Correct Answer ATP, adenosine
GABA is a NT AA that is just modified __________ Correct
Answer glutamate
Gas NT Correct Answer NO, CO, H2S
