Which of the following treatments has the highest potential to provide total pain relief?

1. Chiropractic manipulation
2. Neuronal injection of alcohol
3. Acupuncture
4. Transcutaneous electrical nerve stimulation (TENS)

Question 2

Identify the correct statement regarding the neural mechanism of pain

1. Once the pain impulse reaches the spinal cord, neurotransmitters inhibit the signal.
2. Alpha fibers are wrapped in myelin; C fibers are not.
3. When tissues are damaged, pain impulses go directly to the brain via alpha and beta fibers.
4. Myelin is a substance that slows nerve transmission.

Answer to Question 1

Correct Answer: 2
Rationale: TENS, chiropractic manipulation, and acupuncture are less likely to provide total pain relief. Nerve blocks irreversibly stop impulse transmission along the treated nerves.

Answer to Question 2

Correct Answer: 2
Rationale: A pain impulse travels to the spinal cord via alpha and C fibers. The alpha fibers are wrapped in myelin (a lipid substance that speeds nerve transmission); the C fibers are not. Once the impulse reaches the spinal cord, neurotransmitters pass the message along to the next neuron.
