This figure depicts the EMG responses of the TP, CP, and diaphragm in a minimally restrained awake chronically instrumented dog. Throughout this recording the dog is lying prone with its head upright or resting down on its paws. Note that the CP but not TP EMG varies with head position, and when the dog is relaxed at rest with its head down the TP EMG exceeds the CP EMG. TP, thyropharyngeus; CP, cricopharyngeus; Dia-D, diaphragmatic dome fibers.
