Correct!
Middle cerebral artery
Posterior communicating artery
Anterior communicating artery
Circle of Willis
Dysphasias usually are associated with cerebrovascular accident involving the middle
cerebral artery or one of its many branches.
Question 2
2 / 2 pts
Vomiting is associated with CNS injuries that compress which anatomic location(s)?
Vestibular nuclei in the midbrain
Diencephalon
Correct!
Vestibular nuclei in the lower pons and medulla oblongata
Floor of the third ventricle
Vomiting is associated particularly with CNS injuries that (1) involve the vestibular nuclei
(located in the lower pons and medulla oblongata) or their immediate projections,
particularly when double vision (diplopia) also is present.
Question 3

Cognitive operations cannot occur without the _____ functioning.
cingulate gyrus
pons
Correct!
reticular activating system
medulla oblongata

environment, and affective states (i.e., moods). Consciousness often is viewed as
comhaving two distinct components: arousal and awareness. Arousal, an attentional system,
is the state of awakeness that an individual exhibits. Level of arousal is mediated by the
reticular activating system.
Question 4

Dilated and sluggish pupils, widening pulse pressure, and bradycardia are clinical findings evident of
which stage of intracranial hypertension?
Correct!
Stage 3
Stage 1
Stage 2
Stage 4
Stage 3 of intracranial hypertension presents clinical manifestations that include
decreasing levels of arousal, Cheyne-Stokes respiration or central neurogenic
hyperventilation, pupils that become sluggish and dilated, widened pulse pressure, and
bradycardia.
Question 5
2 / 2 pts
Which description is consistent with a complex partial seizure?
Alternative tonic and clonic movements
Correct!
Consciousness is impaired as well as the ability to respond to exogenous stimuli
One seizure followed by another in less than 1 minute
Focal motor movement without loss of consciousness
