उत्तर १

In the case of a spinal cord injury, the signals coming from the nerves as well as the signals coming to the receptors will be disrupted. As both of these signals meet in a bundle in the spinal cord, so there is any spinal cord injury, then both of these signals are disrupted.

उत्तर २

The reflex arc connections between the input and output nerves meet in a bundle in the spinal cord. In fact, nerves from all over the body meet in a bundle in the spinal cord on their way to the brain. In case of any injury to the spinal cord, the signals coming from the nerves as well as the signals coming to the receptors will be disrupted.
