Many organs and tissues in the body can recover after injury without intervention. Why can’t the central nervous system repair itself after injury? Fractured bones can lead to further damage and the possibility of infection. The swelling makes the injury worse unless it is rapidly relieved. When an injury to the central nervous system occurs, the soft tissue of the brain and spinal cord swells, causing pressure because of the confined space. Unfortunately, this protection can be a double-edged sword. A fluid-filled space below the bones, called the syrnix, provides shock absorbance. Its main line of defense is the bones of the skull and spinal column, which create a hard physical barrier to injury. The central nervous system is better protected than any other system or organ in the body. How does the central nervous system protect itself from injury? It is also the core of our thoughts, perceptions, and emotions. It controls all voluntary movement, such as speech and walking, and involuntary movements, such as blinking and breathing. Most systems and organs of the body control just one function, but the central nervous system does many jobs at the same time.
How does the central nervous system differ from other systems of the body? When the spinal cord is injured, the exchange of information between the brain and other parts of the body is disrupted. The spinal cord is the highway for communication between the body and the brain. Like a central computer, it interprets information from our eyes (sight), ears (sound), nose (smell), tongue (taste), and skin (touch), as well as from internal organs such as the stomach. The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement. It consists of two parts: the brain and the spinal cord. The central nervous system (CNS) controls most functions of the body and mind.
