Final answer:
Hemiparesis is a condition characterized by weakness or paralysis on one side of the body, often resulting from spinal cord damage. In the case of a traumatic injury to the neck, hemiparesis may occur if there is damage to the motor pathways of the brain or spinal cord. This condition can lead to hemiplegia on the side of the trauma.
Step-by-step explanation:
Hemiparesis is a condition characterized by weakness or paralysis on one side of the body. It occurs due to damage to the motor pathways of the brain or spinal cord. In the case of a traumatic injury to the neck, hemiparesis may result from spinal cord damage. This can happen when there is a fracture or crush injury to the vertebrae, and debris penetrates or sections through part of the spinal cord.
In the event of a hemisection (damage to only half of the spinal cord), one leg would be paralyzed, resulting in hemiplegia.
