The spinal cord receives messages from sensory neurons. The brain then receives a message from the spinal cord. Finally, the brain sends a reaction through motor neurons, which prompt the knee muscles to contract and kick out. Part 2: The stimulation is similar to Part 1, but this time, the Achilles is activated, causing the heel and toes to move in opposite directions as a result. Part 3: Similar to Parts 1 and 2, this stimulation involves striking the bottom of the foot with a hammer. The foot's toes turn inward as a result of this. Part 4, The stimulus in this instance is the light. The rods and cones of the eye are stimulated after it enters the eye.
