___________ strokes usually have a worse prognosis for
survival or recovery. May involve coma, lesions of CNs, lesions
of descending motor or ascending sensory pathways. -
ANSWER-Brainstem
The prognosis of a brainstem stroke depends on what? -
ANSWER-Location and size of lesion as well as amount of
collateral blood flow and early medical care
The four D's with crossed findings? - ANSWER-Diplopia,
dysarthria, dysphagia, and dizziness (ipsilateral)
______________ pathways send information from the brain to
the periphery (motor). - ANSWER-Descending
______________ pathways send sensory information from the
periphery to the brain. - ANSWER-Ascending
What make up the posterior column medial leminiscus? -
ANSWER-The fasciculus cuneatus and fasciculus gracilis
,The fasciculus gracilis carries sensory information from the
__________ extremities. - ANSWER-Lower
The fasciculus cuneatus carries sensory information from the
___________ extremities. - ANSWER-Upper
The _______________ pathway predominantly provides our
protective sensations and pain. - ANSWER-Anterolateral
The dorsal and ventral spinocerebellar tracts send information
from the __________ to the ______________. - ANSWER-Spine,
cerebellum
The posterior column medial leminiscus, anterolateral system
(spinothalamic, spinoreticular, spinomesencephalic), ventral
and rostral cerebellar, dorsal spinocerebellar, and
cuneocerebellar are all ________________ tracts. - ANSWER-
Ascending
What makes up the anterolateral system? - ANSWER-
Spinothalamic, spinoreticular, and spinomesencephalic tracts
The _______ is responsible for sensory (vibration, joint
position, and fine touch). - ANSWER-PCML
, Where does the PCML cross over? - ANSWER-Internal arcuate
fibers (lower medulla)
The anterolateral pathway is responsible for ________,
________________, and _________ ________. - ANSWER-Pain,
temperature, crude touch
Where does the anterolateral pathway cross over? - ANSWER-
Anterior commissure in the spinal cord
What is the difference between the spinothalamic, reticular, and
spinomesenteric tracts? - ANSWER-Spinothalamic: ex. feeling
that you stepped on something sharp
Reticular: ouch that hurt (emotional component)
Spinomesenteric: pain modulation ("that's better")
Meissner's corpuscle vs Merkel's? - ANSWER-Meissners: light
touch
Merkerls: two point discrimination
Pacinian corpuscles and ruffini endings deal with __________
and ________ ________. - ANSWER-Vibration and deep touch
