Question

Quizplus · Accepted Answer

A spinal cord injury at the level of C2 affects the phrenic nerve, which controls the diaphragm, resulting in an inability to breathe on their own. This injury causes quadriplegia, affecting all four limbs and the torso. Hemiplegia (paralysis of one side of the body) and blindness would typically result from injury or damage to the brain, not the spinal cord at this level. Paraplegia (paralysis of the lower body) and deafness are also not associated with an injury at the C2 level. Ptosis of the eyelid and dilated and fixed pupils are potential symptoms of a traumatic brain injury or damage to the third cranial nerve, which is not typically associated with a spinal cord injury at the C2 level.
