A transsection of the spinal cord at the C3 level would result in the loss of both sensory and motor function below that level. Additionally, because the phrenic nerve, which innervates the diaphragm, originates from the C3 to C5 spinal levels, a transsection at C3 would likely impair the person's ability to breathe independently, making them ventilator-dependent.
