NURS 751 Exam I Questions and Answers Already Passed Latest Update 2025-2026
Role of neurotransmitters in CNS - Answers -neurotransmitter=chemical agent acts as
messenger at synapse
transfers from presynaptic neuron to postsynaptic neuron
where are neurotransmitters released? - Answers synaptic cleft
what causes release of neurostransmitter? - Answers electric activity/action potential
what are 2 phases of action potential? - Answers depolarization - initial phase of action
potential/excitatory response when Na and CA ions flow into cell
repolarization - restoration phase/inbitory response when K leaves cell or CL enters cell
What contributes to psychiatric symptoms at the synapse? - Answers problems with structure
or chemistry of the synapse which interrupts normal flow of impulses and stimuli.
What are included in the monoamines? - Answers serotonin, dopamine, norepinephrine,
epinephrine
Where is dopamine produced?
What is precursor of dopamine?
How is it removed from synaptic cleft?
What are 4 dopaminergic pathways? - Answers substantia niagra; ventral tegmental
precursor - tyrosine
removed by monoamines oxidase enzymatic action
mesolimic, mosocortical, nigrostriatal, tuberinfundibular
Function of dopamine? - Answers executive function
motor control
motivation
arousal
reward
, serotonin production - where? - Answers produced in raphe nuclei of brainstem
what is serotonin a precursor to? - Answers tryptophan
What is sertonin mainly associated with in psyche? - Answers mood and axiety disorders
What is brain tissue composed of? - Answers Gray matter and white matter
what is gray matter comprised of? - Answers cell bodies and dendrites
working area of brain and synapses
area of neuronal connection
what is white matter comprised of? - Answers myelinated axons of neurons
What connects the right and left hemispheres of cerebrum? - Answers corpus callosum
area of sensorimotor info. exchange between hemispheres
What are functions of frontal lobe? - Answers motor function - voluntary motor activity of
specific muscles
premotor area - muscles, movement, coordination
association cortex - allows multimodal sensory input that trigger memory/decision making
Executive functions: working memory, reasoning, planning, prioritizing, sequencin behavior,
insight, flexibility, judgement, impulse control, behavioral cueing, intelligence, abstraction
What does association cortex allow for? (frontal lobe) - Answers multimodal sensory input
triggers memory/decision making
what kind of language is frontal lobe and where? - Answers expressive - Boca
where is personality developed? - Answers frontal lobe;
problem in frontal lobe leads to in psyche? - Answers personality, intellectual and emotional
changes
What is temproal lobe function? - Answers auditory
language - wernickes area receptive/comprehensive language
memory
vision/sensory integration
