Central Nervous System Injuries

The Central Nervous System (CNS) consists of the brain and spinal cord. In general terms, the cortex of the brain is responsible for information processing. It both integrates and responds to sensory information from the environment. It controls everything from voluntary movement to speech to personality and vision. Below that, as the brain transitions to the spinal cord, is the brain stem. The brain stem is made up of the medulla oblongata, pons, and cerebellum. The cerebellum is important in balance and motor function, the pons is involved in sensory analysis and motor control as well as sleep and consciousness. Finally, the medulla oblongata takes care of most of our involuntary functions such as breathing, heart rate control, etc (Bryn Mawr College, 2005).

Injury to the CNS can have profound and often baffling consequences. Stroke, for instance, can cause lose of sensation, loss of motor function, inability to control the bowel and bladder, changes in speech, changes in personality, inability to see, and more. Damage to the brain can affect personality and cognition while damage to the spinal cord only affects motor function and sensation. Understanding the functions of specific areas of the CNS can help to understand how injury to those areas will manifest itself. As a final note before getting into the specifics, it is a general rule that the CNS does not heal. Thus, any injury to the CNS that results in cell death (death of neurons) is usually ...
