Register to read the introduction… Bailey, 2013) is the brain stem. This is the simplest part of the human brain. Some animals’ entire brains, such as reptiles – who appear early on the evolutionary scale – resemble our brain stem. It is made up of the midbrain, pons, and medulla (P.A. Kinsler, 2012). The brain stem controls consciousness, respiration, heart rate, eye movement, dilation and constriction of the pupils in response to light and darkness, swallowing and facial movement and all neurological signaling from the brain to various muscle groups. An injury to the brain stem is severe and highly dangerous because it is similar to the motherboard of a computer being disrupted or destroyed. The brain stem literally controls all that we do and how we process the things that we do (Dynaslint.com, 2012). Although a discussion of the inner brain (consisting of the: corpus callosum, thalamus, hypothalamus, amygdala, and the hippocampus – the limbic system) is surly relevant to the discussion of TBI, it is far too involved for our discussion here. We will therefore omit that discussion except to say that all traumatic brain injury will no doubt have serious effects on the functions of these areas, and there will be interconnected …show more content…
They are classified as either mild, moderate, or severe, depending on severity. They can also be classified by whether there was loss of consciousness or not, or by whether it resulted in coma or not. Further still, some classify them by whether there is a penetrating injury or broken skull bone, or simply brain swelling. Yet, however, you classify it; the recovery from a TBI can range wildly. It is still largely a mystery as to why a seemingly minor bump or blow to the head can result in traumatic injury with extensive and lasting damage and rehabilitation, while other seemingly catastrophic head injury victims make a relatively quick and full …show more content…
There is great risk for loss of mental capacity, motor control, emotional response, and memory – both short and long term. The thought that our very personality – emotions, sense of humor and so forth – all the things that make us an individual and the person that our friends and family know and love is so disturbing as to be unthinkable. The brain is so complex and its functions so subtle that any changes, particularly injury is potentially fatal and likely life altering. Because there are still so many unknown variables involved, prevention of TBI’s is still the best course of action. Should one suffer a traumatic brain injury, however, all involved must prepare for a long and difficult road to
