brain and spiral cord
The third type of this virus affects the brain and spinal cord. Only about 1-2% of people get this far when getting the virus (Wilson 3). This way will kill you but in a slower and more painful way that any other process of having polio. There is also more suffering. It could take days or weeks but the patient will eventually collapse and die. This is called paralytic poliomyelitis (Wilson 3). It means that this process will make patients bones completely unable to move and eventually to even breath (Wilson 3).
steps:
Once in the body it damages /destroys specialized nerve cells called anterior horn cells (Wilson 3). These cells are a key link in the motor never system that transmits messages from the brain to muscles telling them to contract or relax so we can move (Wilson 3).
When these cells are damaged or destroyed the nerves serving a particular set of muscles cease to function and the muscle is paralyzed (Wilson 3). The extent of paralysis is determined by the damage and destruction. (If the nerves are just damaged the patient will recover over time) (Wilson 3).
When the nerve is destroyed by polio, the paralysis is permanent since nerve cells are unable to regenerate (Wilson 3).
If only a few nerve cells are destroyed, the patient will experience weakness in that muscle because many nerve cells take care of major muscle systems in the body (Wilson 3).
