CNS Vasculature Flashcards
(31 cards)
Anterior carotid system
Cortex, white matter, subcortical structures
Posterior (vertebro-basilar) system
Spinal cord, brainstem, cerebellum
Collateral circulation
Area supplied by multiple sources
Vertebral artery supply
Spinal cord, medulla, cerebellum
Anterior and Posterior spinal arteries
Spinal cord
Posterior Inferior Cerebellar Artery (PICA)
Dorsolateral medulla, cerebellum
Basilar Artery
Pons, cerebellum (medulla?)
Anterior Inferior Cerebellar Artery (AICA)
Dorsolateral pons, cerebellum
Superior Cerebellar Artery
Midbrain, cerebellum
Posterior Cerebral Artery
Inferior surface, occipital lobe
Circle of Willis
Collateral circulation between anterior and posterior systems
Posterior Communicating arteries
Connects anterior w/ posterior systems
Internal Carotid
Major source of anterior system
Middle Cerebral artery
Lateral fissure and lateral aspects of cortex (upper body, face)
Anterior Cerebral Artery
Medial surface of hemispheres (lower body motor cortex)
Anterior Communicating Artery
Medial; connects anterior cerebral arteries
Superior Sagittal sinus
Superior surface of frontal, parietal, occipital lobes
Inferior sagittal sinus
Inferior margins of Falx Cerebri
Arachnoid villi/granulations
outflow of CSF into superior sagittal sinus
Choroid plexus
CSF production
Lateral ventricle
C-shaped ventricle in frontal, parietal, temporal and occipital lobes
Interventricular Foramen
Connects lateral with IIIrd ventricle
Third Ventricle
Medial wall of diencephalon
Cerebral Aqueduct
Midbrain; connects IIIrd and IVth ventricles
