Popis:	Rapid relaxation (shortening) of the femoral chordotonal organ in Cuniculina impigra Redtenbacher induces a depolarization followed by hyperpolarization of the fast and slow extensor tibiae motor neurons (FETi and SETi). The initial depolarization is caused by acceleration-sensitive units of the chordotonal organ. The reverse sequence of responses is induced in flexor motor neurons. The common inhibitor neuron (CI) is depolarized by both lengthening (stretch) and relaxation of the chordotonal organ. The initial depolarization of FETi and SETi and the initial hyperpolarization of flexor motor neurons produced by rapid relaxation of the chordotonal organ and the depolarization of CI produced by lengthening of the chordotonal organ all oppose the resistance reflex response. However, these assisting components are weak compared to the resisting ones.
