Answer
The answer for #14 is crossed extensor reflex.
Work Step by Step
If one steps on a a tack, glass splinter, or other sharp object, a nociceptive signal will be sent to the spinal cord on the side of the injury. In reaction, the limb on that side will be flexed and withdrawn. Almost simultaneously, as sensory pain impulses enter the spinal cord from the injured limb on one side, motor impulses will go out to the limb on the contralateral side. In response, the contralateral limb will extend reflexly. This is a well-known example of the crossed extensor reflex. The reflex extension of the contralateral limb is made to coincide with flexion of the injured limb.
