Identify the proper path of the main pain pathway, beginning with the site of injury and ending at the point where the person becomes aware of pain.

A. Injured tissues stimulate nociceptors; the pain signal then travels to the dorsal horn of the spinal cord; the spinothalamic tract relays the pain signal to the thalamus; the thalamus relays the pain signal to the postcentral gyrus.

B. Injured tissues stimulate nociceptors; the pain signal travels to the dorsal horn of the spinal cord; the spinoreticular tract relays the pain signal to the thalamus; the thalamus relays the pain signal to the postcentral gyrus.

C. Injured tissues stimulate nociceptors; the pain signal travels to the spinoreticular tract; the spinoreticular tract relays the pain signal to the hypothalamus and limbic system.

D. Injured tissues stimulate the dorsal horn of the spinal cord; the spinothalamic tract stimulates the spinoreticular tract; the spinoreticular tract stimulates the thalamus; the thalamus relays a signal to the limbic system.
