The answer is contralateral. It means that the reflex happens on
the contradictory side of the body from the stimulus. To produce this reflex, divisions
of the afferent nerve fibers cross from the stimulated side of the body to the
contralateral side of the spinal cord. There, they synapse with interneurons,
which, in turn, excite or prevent alpha motor neurons to the muscles of the
contralateral limb.
