The deep temporal nerves (Nn. temporales jjrofundi) (Fig. 562), two or three in nmnlier, arise from, or by a common trunk with, the mSfeseteric. They supply the temporalis muscle. 3. The buccinator nerve (N. buccinatorius) passes downward and forward at first across the medial surface of the temporo-mandibular articulation, then through the anterior part of the lateral pterygoid muscle, then between the bucci-.
