I investigated the human masseteric jaw jerk reflex mechanism using an electrode array in the stomatognathic system. The response varied with location and contraction level, and there was no difference in latency between the two sides. I also investigated the relationship between motor nerves and masseter muscles. Electrical stimuli were applied to the masseteric nerve from the skin at the mandibular notch. I observed the M-wave, which is the so-called distal mother latency (DML), and M-wave peaks propagated from the motor end-plate. I found that the muscle fiber conduction velocity (MFCV) decreased with fatigue. DML and MFCV were useful parameters for estimating nerve and muscle conditions.
