Blood is supplied to the brain by what 2 major arteries:
Internal carotid and vertebral arteries.
Carotid arteries branch to supply:
frontal, parietal, and temperol lobes, basal ganglia, thalamus, and hypothalamus.
Vertebral arteries supply:
Middle and lower temperol lobes, occipital lobes, cerebellum, brain stem, part of the diencephalon.
The hardening and thickening of arteries and is a major cause of a stroke.
Transient Ishemic Attack (TIA)
Temporary focal loss of neurologic function caused by ishemia.
Cerebral thrombosis is a narrowing of the artery by fatty deposits called plaque which causes a clot to block the passage of blood through the artery.
Clot that reaches an area to narrow and it blocks the flow of blood.
Blood vessel bursts and lets blood seep into the damaged brain tissue.
