Posterior Cerebral Artery (PCA) - Answer Arises from basilar. Supplies Occipital
Lobe , Midbrain, Thalamus,
... [Show More] Pineal Gland, Choroid Plexus, and Corpus Callosum
Symptoms of PCA Stroke - Answer -Contralateral Visual Field Homonymous
hemianopia
-Visual Agnosia (unable to interpret/recognize visual information)
- Weber's Syndrome (3rd nerve palsy + contralateral hemiplegia)
-Parinaud's Syndrome (Impaired upwards gaze, convergence-retraction nystagmus,
primary conjugate downward gaze)
Anterior Inferior Cerebellar Artery (AICA) - Answer Feeds anterior inferior parts of the
cerebellum
Symptoms of AICA Stroke - Answer Lateral Pontine Syndrome: vertigo, vomiting,
nystagmus, falling towards the side of the lesion, ipsilateral loss of sensation to the
face, ipsilateral facial paralysis, ipsilateral hearing loss
Posterior Inferior Cerebellar Artery (PICA) - Answer Feeds cerebellum, superior
section of the medulla,. Choroid plexus and fourth ventricle
Symptoms of PICA Stroke - Answer Wallenburg Syndrome (lateral Medullary
Syndrome): Loss of pain and temperature sensation in the contralateral trunk and
ipsilateral face
Basilar Artery - Answer An artery, formed by the fusion of the vertebral arteries, that
supplies blood to the brainstem (medulla and pons) and to the posterior cerebral
arteries.
Symptoms of Basilar Artery Stoke - Answer Coma, quadriparesis, ataxia, dysarthria,
CN dysfunction and visual deficits, Locked in Syndrome, Intranuclear
Opthalmoplegia, gaze paresis, Millard Gulber Syndrome CN VI VII damage (diplopia
facial weakness, loss of corneal reflex), Nausea, vomiting, diplopia, gaze palsy,
dysarthria,. vertigo, tinnitus, hemiparesis, and quadriplegia.
Anterior Cerebral Artery (ACA) - Answer Feeds the media portion of the frontal and
parietal lobes as well as the corpus callosum
Symptoms of ACA Stroke - Answer Contralateral motor/sensory deficits impacting
legs > arms
Middle Cerebral Artery (MCA) - Answer Feeds majority of the frontal, parietal, and
temporal lobes, basal ganglia, internal capsule. It is divided M1 - M4
Symptoms of MCA Stroke - Answer -Aphasia if dominant hemisphere
-Neglect if non-dominant hemisphere
-Contralateral motor/sensory loss of face/arm/leg with Arms > Legs
-Anosognosia: neglect or lack of self awareness [Show Less]
