Your friend hitting his head on a rock and becoming paralyzed from the waist down suggests a disruption in his nervous system. The nervous system is responsible for transmitting signals between different parts of the body, including the brain, spinal cord, and nerves. Injuries to the nervous system can lead to various neurological impairments, including paralysis. In this case, the blow to your friend's head likely caused damage to his spinal cord or nerves, resulting in the paralysis.
