Put the following events of a simple spinal reflex into correct order.

• Afferent fibers carry somatosensory information into the spinal cord via the dorsal horn

• ɑ-motor neurons carry efferent information into the periphery via the ventral horns

• Efferent fibers synapse onto skeletal muscle cells, causing them to contract
