Question

A person sees a ball and kicks it, in part because of actions of the nervous system. Using the parts of the nervous system listed bellow, describe the path of nerve impulses that cause the person to see the ball
• brain
• motor neurons
• sensory neurons
• spinal cord

Answer 1

The signal will start from the eyes. The message is carried by sensory neurons to the spinal cord. There, the "impulse" will transfer to motor neurons which will carry it to the brain. So in short:

Sensory neurons --> spinal cord --> motor neurons --> brain
