In brain injury, there is typically an event in the brain which can be from disease or trauma. Injury in the spinal cord results in collapse or damage to the spinal cord tissue as the vertebral bones are also rigid. The same principle applies in that there is only room for the spinal cord, blood flow and cerebral spinal fluid. These bones are articulated to accommodate body movement. Similarly, the spinal cord is housed in the bony vertebrae or spinal bones. Another issue is that the swollen brain tissue can drop through the largest opening in the skull at the brainstem thereby damaging it. The sensitive brain tissue will collapse as the extra fluid presses against it, leading to more damage.
Therefore, something less rigid than the skull will need to shift due to the extra load. When an injury occurs to the brain, there can be an increased amount of blood, fluid, inflammation or even air which cannot be accommodated. There is absolutely no room for anything else. The skull has room for the brain, blood flow and the cerebral spinal fluid that cushions it. The brain is encased in the ridged bone of the skull.
That is a clue to their importance and need for protection. Notice these are the only two body organs that are completely housed in bone. Therefore, the body is built to provide them with the utmost protection, complete bone encasement. The brain and spinal cord are extremely delicate. Since the brain and spinal cord work together and are similar in tissue consistency, these two organs need to be discussed together. The central nervous system (CNS) consists of the brain and spinal cord. A head injury can be any bump, cut or bruise to any part of the head but not extending into the brain. A brain injury caused by an accident or intended harm is called a traumatic brain injury (TBI). When a BI is caused from a medical issue such as a stroke, tumor, metabolic issue or other medical diagnosis, the term, acquired brain injury (ABI) is used. BI specifically indicates harm to the brain.
