NURS 307 FINAL Questions with Detailed
Verified Answers
What leads to brain dysfunction? Ans: expression and behavioural symtoms
Comparative research approach Ans: Compared with other life forms
Developmental research approach Ans: Changes in the nervous system throughout
the life span
Cytoarchitectural research approach Ans: Distribution and arrangement of cells
within various parts of the brain
Chemoarchitectural research approach Ans: Identification of neurotransmitters or
chemicals
Functional research approach Ans: localized function
Neurtransmitters Ans: Small molecules directly or indirectly responsible for opening
or closing ion channels.
Neurplasticity Ans: how function can be restored over time after brain damage occurs
or how
individual may react over time to psychotherapy of continuous pharmacotherapy
regimen
Plasticity Ans: is the ability of the brain to change its structure and function in
response to internal and external
pressures
,T or F: The ability of the brain and nervous tissue to adapt and change refers to its
plasticity. Ans: True
Structural Neuroimaging Ans: visualization of the brain
CT/MRI
Functional Neuroimaging Ans: Radioactive Measurement of physiologic activities
PET/SPECT
Neuroanatomy of the CNS Ans: Cerebrum
l/r hemispheres, lobes
Subcortical Structures Ans: Basal ganglia
Limbic system
Hippocampus
Thalamus
Hypothalamus
Amygdala
Limbic midbrain nuclei
MRIs and CTs are used to do which of the following tasks?

,A. Structural neuroimaging
B. Functional neuroimaging
C. Psychological neuroimaging
D. Profiling Ans: A
Neurons of the ANS Ans: -Efferent or motor system nerves (nerves moving away
from the CNS)
- Afferent or sensory (nerves moving towards the CNS)
- Sympathetic
- Parasympathetic
Receptor subtypes: Ans: Each major neurotransmitter has several different subtypes
for the chemical, allowing for
different effects on the brain.
- Each major neurotransmitter has several different subtypes (e.g., dopamine: D1, D2).
Neurotransmitter Criteria Ans: • Synthesized inside the neuron.
• Present in the presynaptic terminal.
• Released into the synaptic cleft, causing a particular effect on the postsynaptic
receptors.

, • An exogenous form of the chemical is administered as a drug, which causes identical
action.
• Chemical is removed from the synaptic cleft by a specific mechanism.
Synthesized from tyrosine Ans: - Dopamine
- Norepinephrine
- Epinephrine
Synthesized from tryptophan Ans: Serotonin
Synthesized from histidine Ans: Histamine
Dopamine Ans: Excitatory Neurotransmitter
• Found in distinct region of the CNS (mesocortical)
• Involved in cognitive, motor & neuroendocrine functions Dopamine level are
decreased in Parkinson's
disease
• Abnormal dopaminergic activity associated with schizophrenia.
• Dopamine is also the neurotransmitter that stimulated the body's natural feel reward
pathways producing
pleasure and euphoric sensation under certain conditions
