Cerebral Vascular Aneurysms and Accidents The brain is the most complex organ in the human body, but perhaps the most remarkable. Our brain is the primary control center, containing billions of nerves that can simultaneously process information from our body, operate organs, generate emotions and thoughts, recall and store memories, and control movement. The brain also contains many blood vessels that supply the brain with oxygenated blood to keep it functioning. If something happens to your brain that interrupts blood flow, your brain will only be able to survive four to six minutes. Even though the brain has several layers that protect it, it can be injured. Brain injuries can occur in a variety of ways, with the most common being blunt force trauma. Brain injuries can occur even without blunt force trauma, such as aneurysms and cerebral vascular accidents. Aneurysms and CVAs occur with or without trauma, but several treatment options exist. The head has several layers that protect the brain. The first layer you might consider for protection in most people is your hair. Of course some people don't have hair, so the next protection is skin. Let's now move on to the main protection which is the skull or cranium. Your skull, which is a hard bone, is the best protection for any penetrating or blunt trauma it may cause. It also serves to prevent the brain from moving much. The skull is made up of four bones: frontal, temporal, parietal, and occipital (posterior). In pediatrics, people need to pay special attention to head injuries. The pediatric baby's skull is still soft and not completely fused together. The baby's anterior fontanelle usually merges together around the age of nine to eighteen months, where the posterior fontanelle... center of the card... geons. (2011).
