A super-quick reaction happens if you burn yourself on a noodle cup. It is called a spinal reflex arc, and it bypasses the brain to get you out of danger more quickly. On the board, write the 5 steps in this spinal reflex arc (hint. Step 1 is Receptors, Step 5 is Effector).
Step 1 - Receptors detect pain and heat
Step 2 - Sensory neurons transmit the signal to interneurons in the spinal cord.
Step 3 - Interneurons transmit the signal to the motor neuron
Step 4 - Motor neuron sends an electrical impulse to the effector (muscle)
Step 5 - The effector moves your hand away from the hot water. You drop the cup.
