摘要

咀嚼肌来源于一个共同的胚胎,而在颞下窝(ITF)存在附属肌肉的情况并不常见。在这里,我们展示了对 ITF 的尸检解剖结果,发现了一块单侧存在的肌肉,它从蝶骨大翼向下延伸,与翼内侧和翼外侧肌肉相融合,然后附着在翼外侧板上。这块肌肉与最初于 1858 年描述的翼鹅颈本体肌最为一致。虽然这种肌肉的确切胚胎学起源和功能仍有待推测,但这些问题仍值得研究,因为它可能为第一咽弓下降肌肉的本体发育提供启示。此外,翼侧本体肌的存在可能会产生临床意义并影响周围结构,如三叉神经的下颌分部、上颌动脉、翼静脉丛、咀嚼肌和颞下颌关节(TMJ)。

Pterygoideus proprius muscle: stuck between the greater wing and lateral pterygoid plate.

The muscles of mastication derive from a common embryological source, and the presence of accessory muscles in the infratemporal fossa (ITF) is uncommon. Here, we present findings from postmortem dissection of the ITF revealing a unilaterally present muscle extending from the greater wing of the sphenoid to blend inferiorly with the medial and lateral pterygoid muscles before attaching to the lateral pterygoid plate. This muscle is most consistent with the pterygoideus proprius muscle initially described in 1858. Though the exact embryological origin and function of this muscle remain speculative, these topics are nonetheless worth investigating as it may provide insight regarding the ontogeny of muscles descending from the first pharyngeal arch. Additionally, presence of the pterygoideus proprius muscle may have clinical implications and impact surrounding structures such as the mandibular division of the trigeminal nerve, maxillary artery, pterygoid venous plexus, masticatory muscles, and temporomandibular joint (TMJ).

期刊介绍: "Folia Morphologica" is an official journal of the Polish Anatomical Society (a Constituent Member of European Federation for Experimental Morphology - EFEM). It contains original articles and reviews on morphology in the broadest sense (descriptive, experimental, and methodological). Papers dealing with practical application of morphological research to clinical problems may also be considered. Full-length papers as well as short research notes can be submitted. Descriptive papers dealing with non-mammals, cannot be accepted for publication with some exception.
