Fig. 3 — Tracheal muscle tissues strips were subjected to length steps either before (a) or after 1 min of contractile stimulation with ACh (b). Force in response to ACh was much higher when the length step was performed prior to contractile stimulation than when the length step occurred during contractile stimulation.
