Vitti & Basmagian (1977) [18] aimed to analyze comprehensively intramuscular myoelectric activity of muscles: temporal, masseter, medial pterygoid, anterior belly of the digastric, mylohyoid and geniohyoideous in "normal" individuals with bipolar type electrodes "fine wire" during jaw movements, chewing and swallowing.
The spinopterygoidal line extends through the medial margin of foramen ovale to the posterior margin of the medial pterygoid plate (Figure 3).
