The reflex can be evoked in postural muscles.

It is a reflex response to the afferent impulses of tendon organs lying in the tendon being tapped.

This reflex forms the basis for current views about the mechanism of posture.

This reflex involves a chain of two neurones.

It is possible to evoke this reflex by a brisk but light tap on the tendon of the muscle, which then responds with a contraction.
