What is an automatic response that occurs very rapidly and without conscious control? They help to protect your body, such as blinking your eyelids in response to something. A) Somatic response. B) Stimulus. C) Conclusion. D) Reflex. Show Answer Correct Answer: D) Reflex. 8. How do messages travel along a neuron? A) In both directions. B) In random directions. C) In one direction. D) In multiple directions. Show Answer Correct Answer: C) In one direction. 9. Each nerve cell has a CELL BODY. On one side of the cell body are short and slender fibers called DENDRITES that receive messages and carry them to the cell body. From the cell body, the messages travel down to the AXON which transmits the messages away from the cell body to the next neuron. Some axons are about three feet long while others are very short.
