Abstract

Background: That the peroneus tertius muscle (PT) is a separate entity has been debated. PT has been reported to be part of the extensor digitorum longus muscle, part of the extensor digitorum brevis, or a separate muscle. While pigs have a PT as well as primates, there are no reports of its association with the extensor digitorum longus muscle or extensor digitorum brevis.

Materials and methods: In this study, we used gross dissection and Sihler's staining to determine the origin, course, insertion, and innervation of the pig PT.

Results: The PT and extensor digitorum longus muscles jointly originated from the femur and ran between the tibialis cranialis and peroneus longus muscles. The PT was inserted at the retinaculum of the metatarsal extensors, tarsal bone, and second metatarsal bone. The branches of the common fibular nerve to the extensor digitorum longus muscle were distributed to the PT.

Conclusions: The innervations suggest that the PT and extensor digitorum longus muscles of the pig were derived from the same muscle mass during development but were named separately due to differences in their morphology. Furthermore, morphological features suggest that pig PT and human PT are probably different muscles.

根据起源、走向、插入和神经支配对猪的腓肠肌进行比较研究。

背景：腓总肌（PT）是否是一个独立的实体一直存在争议。有报道称，腓肠肌是趾长伸肌的一部分、趾短伸肌的一部分或单独的肌肉。虽然猪和灵长类动物一样也有 PT，但没有关于 PT 与趾长伸肌或趾短伸肌相关的报道：在这项研究中，我们采用大体解剖和西勒染色法确定猪 PT 的起源、走向、插入和神经支配：结果：PT和趾长伸肌共同起源于股骨，位于胫骨头肌和腓肠肌之间。PT 插入跖伸肌、跗骨和第二跖骨的胫骨网处。腓总神经到趾长伸肌的分支分布到 PT：结论：神经支配表明，猪的腓肠肌和趾长伸肌在发育过程中来自同一块肌肉，但由于形态不同而分别命名。此外，形态特征还表明猪的伸拇肌和人的伸拇肌可能是不同的肌肉。

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.
