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

• Sensory receptors sense changes in muscles, tendons, skin, etc.

• Afferent fibers synapse onto interneurons and/or ɑ-motor neurons in the gray matter of the spinal cord

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