6501 Advanced Patho- Chapter 17
Damage to the cerebellum causes intention tremor and ataxic gait. - answer intention
tremor and ataxic gait.
Cheyne-Stokes respiration involves - answer a hyperventilatory response to stimulation
by carbon dioxide
Aphasia - answer Loss of language production or comprehension
Chorea - answer Involuntary rapid contractions of muscle groups in a random pattern
Agnosia - answer Impaired recognition of tactile, visual, or auditory stimuli
Tremor - answer Involuntary rhythmic, oscillating movement of a body part
Myoclonus – answer Shocklike, no patterned muscle contractions causing limb
movement; may occur during sleep
Apraxia - answerInability to perform purposeful or skilled motor actions
Athetosis – answer Involuntary slow, twisting, writhing movements
Akathisia - answerMotor restlessness; compulsion to move lower extremities
When autoregulation of intracranial arterioles fails, small increases in blood volume
cause intracranial pressure to rise - answersmall increases in blood volume cause
intracranial pressure to rise greatly
Changes in the pupils are useful to evaluate brainstem function because - answerthe
areas that control arousal are located nearby
Inflammation from brain injury causes vasogenic cerebral edema. - answervasogenic
cerebral edema.
Hypertonia is caused by - answerdamage to upper motor neurons when the lower motor
neurons remain functional.
Lateral corticospinal tract damage causes - answerspasticity
Extrapyramidal motor syndromes involve - answerabnormal movement
