The MC1 [meropodite-carpopodite 1] chordotonal organs of Jasus novaehollandiae and Trizopagurus strigimanus have a close and extensive association with the tendon of the flexor muscle of the pereiopod. Contraction of the flexor muscle in the absence of joint movement causes a number of units in the MC1 nerve to respond to both increasing and decreasing tension. Some small units in the MC1 nerve provide an analog of muscle tension. The movement responses of some units of the MC1 organ are modified by tension:some responses are augmented, others reduced or abolished.
