Direct motor and reflex EMG responses were recorded from facial muscles in monkeys subjected to stimulation of the communicating ramus of the auriculo-temporal nerve. Transection of the ramus distal to the stimulus site eliminated the direct motor response. Transection of the ramus proximal to the stimulus site eliminated the reflex component. The results suggest that the trigeminal nerve carries motor fibres serving facial muscles.
