Final answer:
A common cause of central cord syndrome is traumatic injury, often from car accidents, sports, or diving, leading to potential paralysis and permanent disability due to the limited regenerative capacity of spinal nerves. Option 3.
Step-by-step explanation:
A common cause of central cord syndrome is traumatic injury. This can include car crashes, sports accidents, and diving incidents, which can lead to severe damage to the spinal cord. As a result of such injuries, paralysis may occur depending on the location and severity of the spinal cord damage, making it difficult for messages to travel between the brain and the body. Since the spinal nerves do not regenerate effectively after injury, the resulting disabilities can be permanent, emphasizing the critical nature of prevention and novel research areas such as stem cell transplantation and inflammation reduction strategies.
