【摘要】 本文基于肌电技术研究翼外肌两头功能后所引起的争论,对国人翼外肌进行了大体解削观测和活体肌电活动测试。其结果为:翼外肌的两个头有各自独立的起点,部分上头和下头的纤维虽有共同的止点,但两者的纤维无交叉,各有完整的肌外膜包绕。翼外肌的上、下头在下颌升降时为拮抗肌;在前伸、后退及侧方运动时为协同肌。更多还原

【Abstract】 This article studies morphology and function of the two heads of the lateral pterygoid muscle. Anatomic observation shows that each head of the muscle has the basis of independent function. Electromyographic observation shows that the two heads of the muscle plays different roles in mandibular movement.更多还原
