Final answer:
A complete spinal cord transection injury leads to paralysis characterized by the inability to move voluntarily and the loss of sensation below the injury level.
Step-by-step explanation:
A complete spinal cord transection injury typically causes a loss of the ability to move voluntarily and a loss of sensation below the level of injury. This type of injury disrupts the communication between the brain and the parts of the body below the injury site. As a result, individuals with such an injury will experience paralysis, which includes both loss of voluntary movement and sensation in the affected areas.
