A lesion of the spinal cord that results in paralysis of certain areas of the body, along with the corresponding loss of sensation.
Difference between Paraplegia and Quadriplegia

Paraplegia: Refers to paralysis from approximately the waist down.
Quadriplegia: Refers to paralysis from approximately the shoulders down. Most spinal cord injuries result in loss of sensation and function below the level of injury, including loss of controlled function of the bladder and bowel.
