The diagram above depicts the response to a pinprick (stimulus) on the tip of a human finger. The arrows show the direction of impulse transmission along the labeled axons. If axon II was damaged before the pinprick, which of the following is most likely?
A) The person will not feel the pinprick.
B) The person can no longer feel pain.
C) The person's finger will not withdraw reflexively.
D) The person cannot transmit nerve impulses to the brain.
Answer: C) The person's finger will not withdraw reflexively.
