Neuromuscular: Blood Supply to the Brain Flashcards
Artery that supplies the anterior frontal lobe, medial surface of frontal and parietal lobes
Anterior Cerebral artery (ACA)
ACA impairments
Contralateral lower extremity motor and sensory involvement Loss of bowel and bladder control Loss of behavioral inhibition Significant mental changes Neglect Aphasia Apraxia and agraphia Perseveration Akinetic mutism and significant bilateral involvement
Artery that supplies the outer cerebrum, basal ganglia, posterior and anterior internal capsule, putamen, pallidum, and lentiform nucleus
Middle cerebral artery (MCA)
MCA impairments
Most common site of a CVA Wernicke's aphasia in dominant hemisphere Homonymous hemianopsia Apraxias Flat affect with R hemisphere damage Contralateral weakness and sensory loss of face and upper extremity with lesser involvement in the lower extremity Impaired spatial relations Anosognosia in non-dominant hemisphere Impaired body schema
Artery that supplies portion of midbrain, sub thalamic nucleus, basal nucleus, thalamus, inferior temporal lobe, occipital and occipitoparietal cortices
Posterior Cerebral artery (PCA)
PCA impairments
Contralateral pain and temperature sensory loss Contralateral hemiplegia (central area), mild hemiparesis Ataxia, athetosis or choreiform movement Quality of movement is impaired Thalamic pain syndrome Anomia Prosopagnosia with occipital infarct Hemiballismus Visual agnosia Homonymous hemianopsia Memory impairment Alexis, dyslexia Cortical blindness from bilateral involvement
Artery that supplies lateral aspects of pons and midbrain together with superior surface of cerebellum
Vertebral-basilar artery
Arteries that supply the cerebellum
branches from the basilar artery (PICA, AICA, and superior cerebellar arteries)
Arteries that supply the medulla
PICA and smaller branches from the cerebral arteries
Arteries that supply the Pons
branches from the basilar artery
Arteries that supply the Midbrain and Thalamus
Posterior cerebral arteries
Arteries that supply the occipital cortex
Posterior cerebral artery, basilar artery
Vertebral-basilar artery impairments
Loss of consciousness Hemiplegia/tetraplegia Comatose or vegetative state Inability to speak Locked-in syndrome Vertigo Nystagmus Dysphagia Dysarthria Syncope Ataxia
Wallenberg syndrome
Secondary to lateral medullary infarct
Presents with ipsilateral facial pain, ipsilateral ataxia, vertigo, contralateral pain, and thermal impairment
