Document Summary

Caused by atherosclerosis (plaque build up in the walls of the artery). Described above: know pathway common carotid to internal carotid to aca & mca. External carotid arteries: supplies the face and scalp. Internal carotid supplies: anterior + middle parts of the brain. Internal divides into: anterior cerebral artery (aca) Supplies blood to medial cortex including medial aspects of primary motor area and primary sensory area. Also supplies parts of the frontal lobe and basal ganglia: middle cerebral artery (mca) Supplies blood to lateral aspects of each hemisphere. Lateral aspect or primary motor and sensory area. Know pathway vertebral to basilar to pca & cerebellar ateries. *posterior system: supplies brainstem and back of brain: vertebral arteries- Ascend through the spinal column and then travel besides the brainstem. At the pons they join together to from the basilar artery: posterior cerebral arteries (pca) - Supplies blood to occipital lobes & part of temporal lobes.
