Question: You smell the wonderful aroma of fresh baked chocolate chip cookies. You move your hand to grab a cookie, and OUCH! You jerked your hand away and feel intense pain.

(a) List the motor and sensory pathways (and reflexes: look up flexor reflex) and from your brain to your hand and back again, as well the signal that jerks your hand away.

(b) What sensory receptors are involved, and what are some of the major reflexes, brain targets, and nuclei involved in sensing the information and then sending signals that result in your sensation of pain as well as your hand movements (both the initial reflex and voluntary movement to nurse your hand; list at least 6, more is fine)?

(c) Where are the reflexes localized (does it go all the way to your brain)? What happens first, your hand jerking away, or your realization that you are burned? You may want to consult your textbook's section on reflexes (covered in the spinal cord section chapter 8) and brain pathways (sensory centers in the brain, chapter 8).
