The Human Brain : From Neurone to Nervous System


  1. Spinal cord injuries are commonly associated with fractures and displacement of the vertebral column. 
  2. The injury may cut through axons that carry messages between the brain and the motoneurones, or between the sensory nerves and the cerebral cortex. 
  3. In cases where the cord is totally transacted by the injury there is a total lack of sensory and motor function below the level of injury. In patients with incomplete injury, these functions are partially lost, and some motor or sensory functions below the injury may be retained. 
  4. Control of the bladder and bowel are affected, and the may cause autonomic hyperreflexia (dysreflexia) that can be dangerous.
