Inhibitory interneurons are used to inhibit the contraction of the antagonistic muscles (muscles that oppose the action of the effectors of the reflex) so that they do not contract at the same time as the effectors, which could cause unwanted or harmful movements. This helps to ensure that the movement produced by the reflex is smooth and coordinated.
