To investigate the anatomic attachments to the lateral aspect of the anterior band of the human temporomandibular joint articular disk.
Sixteen human cadaver half-heads were dissected and examined macroscopically.
No direct attachment was observed between the deep masseter muscle and the temporomandibular joint articular disk. In one specimen, a small band of the anterior temporalis muscle was directly attached to the lateral aspect of the temporomandibular joint disk; whereas, on the same specimen, the attachment of the superior belly of the lateral pterygoid muscle was a comparatively large band. In another specimen, the lateral pterygoid muscle passed in an anterolateral direction.
The masseter muscle has no functional significance in the biomechanics of temporomandibular joint disk displacement. The anterior temporalis muscle may have functional significance when it is accompanied by an anterolaterally divergent lateral pterygoid muscle.
研究人类颞下颌关节关节盘前带外侧的解剖附着情况。
解剖16个尸体半头颅并进行宏观检查。
未观察到咬肌深层与颞下颌关节关节盘之间有直接附着。在一个标本中，颞肌前部的一小束肌纤维直接附着于颞下颌关节盘外侧；而在同一标本上，翼外肌上头部的附着则是一条相对较宽的肌束。在另一个标本中，翼外肌向前外侧走行。
咬肌在颞下颌关节盘移位的生物力学中无功能意义。当颞肌前部伴有向前外侧走行的翼外肌时，可能具有功能意义。
