UMKC Neurophysiology IV Part 1 & 2 Questions With
Complete Solutions
>_____% of all neurologic problems are vascular in origin
Correct Answer 50
2 CNS organs Correct Answer brain, spinal cord
2 diseases associated with subcortical nuclei Correct Answer
Huntington's disease, Parkinson's disease
2 types of strokes Correct Answer hemorrhagic, ischemic
All nerve fibers that relay signals between the forebrain,
cerebellum, and spinal cord pass through here; involved in
motor functions, regulation of sleep/wake cycles, focus
attention, integrating center for cardiovascular, respiratory,
swallowing, and vomiting reflexes Correct Answer brainstem
area of the cerebrum that controls behavior, emotions,
motivation Correct Answer limbic association area
axon of neuron Correct Answer nerve fiber
characterized by a wide-based stance and an unsteady, short-
stepped, lurching gait pattern Correct Answer gait ataxia
(alcohol's effect on the cerebellum)
CNS pathway: long axons that carry information between brain
and spinal cord and between large regions of brain Correct
Answer long neural pathways
,CNS pathway: neurons with many axon collaterals and many
synapses; perform complex neural processing (integration)
Correct Answer multisynaptic pathways
collection of several large nuclei; gateway to cerebral cortex;
participates in sensory functions, motor functions, limbic
functions Correct Answer diencephalon
command center for ANS, command center for most of the
endocrine system (via control of pituitary gland), behaviors of
preservation of individual and species, single most important
area for maintenance of homeostasis Correct Answer
hypothalamus
Components of spinal cord white matter Correct Answer
ascending tracts, descending tracts
Cortical area: detects specific sensations (e.g. visual, auditory,
somatic) Correct Answer primary sensory
cortical area: function to transform the intention to perform a
complex motor act into the specific sequence of movements
necessary to accomplish the act Correct Answer secondary
motor
cortical area: makes direct connections with specific skeletal
muscles for causing discrete movements Correct Answer
primary motor
, cortical area: makes sense out of signals received in primary
area Correct Answer secondary sensory
disease in which there is a loss of input from basal nuclei from
cortex Correct Answer Parkinson's disease
disease in which there is a loss of output from basal nuclei to
thalamus Correct Answer Huntington's disease
Found in the outer layer of gray matter of the cerebral cortex.
Increase the surface area of the brain Correct Answer gyri,
sulci
functions to maintain balance and posture, coordinate voluntary
movements, motor learning, cognitive functions Correct
Answer cerebellum
gray matter deep within the cerebral hemispheres (multiple
nuclei), receives most of their signals from cortex and most of
their output goes to cortex via thalamus
Functions:
provides feedback to cortex for development of mvmt
strategies, assist cortex in selection and initiation of purposeful
movement and inhibition of unwanted movement, smoothing out
movement, necessary for automatic performance of learned
repetitive motions Correct Answer subcortical nuclei
Gray matter of spinal cord: where can you find sensory neuron
cell bodies? Correct Answer dorsal root ganglia
