A study of the relationships of the temporomandibular joint disc and the lateral pterygoid, temporalis, and masseter muscles during the human fetal period and in the adult was conducted. The superior head of the lateral pterygoid muscle was seen to insert into the anteromedial two thirds of the temporomandibular joint disc. The fibers of the posterior one third of the temporalis muscle and fibers of the deep bundle of the masseter muscle were attached on the anterolateral one third of the disc. The attachment of these muscles to the disc was through the anterior extension of the disc, also known as the premeniscal or prediscal lamina. The possible functional role of these muscle attachments is discussed.
对人类胎儿期及成人颞下颌关节盘与翼外肌、颞肌和咬肌之间的关系进行了研究。观察到翼外肌上头插入颞下颌关节盘的前内侧三分之二处。颞肌后三分之一的纤维和咬肌深层束的纤维附着于关节盘的前外侧三分之一处。这些肌肉与关节盘的附着是通过关节盘的前部延伸，即半月板前或盘前板实现的。讨论了这些肌肉附着可能的功能作用。
