You stepped on a sharp item on the floor.
The correct sequence of arc reflex which happened is:
I. Effector (muscles) will react by pulling the foot away from sharp item
II. Integrating centre in spinal cord interpret the impulse
III. Receptor on the skin receive the pain sensation
IV. Efferent sends impulse to the effector (muscles)
V. Afferent sends impulse to the spinal cord
