在颏下区的解剖过程中，观察到二腹肌前腹的双侧不对称异常。具体而言，四个额外的肌束之间的二腹肌腹前被发现。虽然二腹肌前腹的异常是经常观察到的，这种复杂的模式，二腹肌异常以前没有报告。我们的研究结果和以前的观察说明了二腹肌的前腹的形态发生的复杂性，来自第一咽弓，从而引起下颌肌肉组织，如下颌舌骨肌。
Bilateral, asymmetric anomalies of the anterior bellies of digastric muscles were observed during dissection of the submental region. Specifically, four extra muscle bundles were found between the anterior bellies of the digastric muscle. Although anomalies of the anterior bellies of digastric muscles are often observed, this complicated pattern of digastric anomalies has not been previously reported. Our findings and previous observations illustrate the morphogenetic complexity of the anterior belly of the digastric muscle derived from the first pharyngeal arch, which gives rise to jaw musculature such as the mylohyoid muscle.
