Question

what happens in paralysis and why ?​

Answer 1

Answer:

Muscle movement is controlled by trigger signals relayed from the brain. When any part of the relay system — such as the brain, spinal cord, nerves, or junction between the nerve and the muscle — is damaged, the signals to move do not make it through to the muscles and paralysis results.
