The art of Frank Capra is very, very simple: It's the love of people. Add two simple ideals to this love of people: the freedom of each individual, and the equal importance of each individual, and you have the principle upon which I based all my films.
Anterior cerebral artery. The anterior cerebral artery supplies most of the superior-medial parietal lobes and portions of the frontal lobes with fresh blood. Blood supply to the brain is essential to its functionality, and a lack of blood flow to the vital processes of the brain can cause serious harm. If blood flow is blocked in the anterior cerebral arteries, paralysis or sensory deficits may occur, or even a stroke. Anterior cerebral arteries supply blood to the frontal lobes' anterior (front) aspects, areas responsible for higher-level cognition, including judgment and reasoning. Blockages of these arteries can result in cerebral dementia and speech difficulties.
At the base of the brain, the carotid and vertebrobasilar arteries form a circle of communicating arteries known as the Circle of Willis. From this circle, other arteriesâthe anterior cerebral artery (ACA), the middle cerebral artery (MCA), the posterior cerebral artery (PCA)âarise and travel to all parts of the brain.Posterior Inferior Cerebellar Arteries (PICA), which branch from the vertebral arteries, are not shown.he vertebrobasilar arteries supply the posterior two-fifths of the cerebrum, part of the cerebellum, and the brain stem. Any decrease in the flow of blood through one of the internal carotid arteries brings about some impairment in the function of the frontal lobes.
