Final answer:
Lesions can be used to determine injury severity. Sensory discrimination and imaging techniques like MRI or CT scanning can help localize the injury. Burn size can guide decisions about treatment.
Step-by-step explanation:
Lesions can be used to determine the severity of an injury. In the case of spinal cord injuries, sensory discrimination can help pinpoint the level of damage. For example, below the hemisection, pain stimuli will be perceived on the damaged side but not fine touch. Imaging techniques like MRI or CT scanning can also localize the injury. Additionally, the size of a burn can guide decisions about the need for specialized treatment.
