翼外肌上头是仅附着于关节盘,还是大部分附着于关节盘,少数肌纤维附着于髁状突。或是大部分附着于髁状突,少数肌纤维附着于关节盘,目前尚存在争论。为此,作者对10具尸颅的20侧颞下颌关节及其周围组织进行了连续切片的组织学观察,结果显示:翼外肌上头与下头在颞颌关节前方融合并在关节的内侧形成强大的肌肉壁。在关节盘前带的外1/3处,未见翼外肌附着;在关节盘前带的中1/3处,翼外肌纤维行经关节盘的下方,附着于髁状突颈部的关节翼肌窝上部;仅于
The outer wing of the wing is only attached to the articular disc, or most attached to the disc, a few muscle fibers attached to the condyle. Or most attached to the condyle, a small number of muscle fibers attached to the disc, there is still controversy. To this end, the authors of 10 corpus 20 sides of the temporomandibular joint and its surrounding tissue sections of the histological observation showed that: the pterygoid top and bottom in the temporomandibular joint anterior fusion and the formation of strong medial joint Muscle wall. At the outer 1/3 of the anterior plate of the articular disc, there was no attachment of the extravertebral muscle. In the middle 1/3 of the anterior disc band, the extraflular muscle fiber passed under the articular disc and the joint wing attached to the condylar neck Muscular upper; only
