按形态解剖学观点，下颌窝（fossa）就是颞下颌关节窝（articular fossa）。它比髁突大，这使髁突无论向前，或是侧方运动时都非常灵活，能在较大的窝 内做回旋运动。

Conclusion at different functional positions of TMJ the relationship of the articular disc with mandibular condyle and the mandibular fossa is different.
结论颞下颌关节不同功能位时关节盘与髁突、关节窝的关系表现不同。
The deformation volume of the articular disc is bigger than that of the glenoid fossa and the condyle.
关节盘的变形量明显大于髁突及颞骨关节窝。
The stresses in the glenoid fossa were the greatest in the back slope of the articular eminence. The regions of the greater compressive stresses of the mandible were those around the force line.
下颌骨较大压应力区位于力的作用线周围区域，较大拉应力区位于下颌支后部及下颌角附近区域。
