肌肉的同源性。最长肌和M.根据对鳞龙类、鳄鱼类和鸟类的详细解剖和已发表的记述，提出了现存双孔类中背部和颈部的髂肋肌群，以及从背部延续到颈部的椎下肌和肋间外肌群。腱的形态和神经支配模式表明，鸟类的“m。背侧区的“髂肋肌”包括两个肌的同源物。最长肌和M.非鸟类双孔类的髂肋肌古颌类鸟类肌腱形态的保守性还表明，鸟类颈区的横突间毫米由两个肌肉组成。最长肌和M.然而，尽管已被视为单一系列的肌肉，但髂肋肌群与鳞龙目或鳄鱼目中同名的肌肉并不同源。位于横突间毫米内侧的鸟类包含毫米与鳞龙类的外肋间毫米以及外肋间毫米和横突间毫米同源。斜角肌与鳄鱼目结合。神经支配模式表明，肌肉（“m。髂肋头肌（iliocostalis capitis）连接寰椎肋骨和枕骨，包括来自椎下层和m的贡献。cucullaris complex，可能还有M.髂肋肌也是目前的研究结果可以作为修改目前使用的鸟类命名法的基础，以便它反映肌肉与非鸟类对应物的同源性。J.

Homologies of muscles of the m. longissimus and m. iliocostalis groups in the dorsal and cervical regions, as well as those of the subvertebral muscles and mm. intercostales externi that continue from the dorsal into the cervical regions, in extant Diapsida are proposed based on detailed dissections and published accounts of lepidosaurs, crocodylians, and birds. The morphology of tendons and innervation patterns suggest that the avian “m. iliocostalis” in the dorsal region include the homologs of both m. longissimus and m. iliocostalis in non‐avian diapsids. The conserved nature of the morphology of tendons in palaeognath birds also revealed that the avian mm. intertransversarii in the cervical region consist of muscles of the both m. longissimus and m. iliocostalis groups despite having been treated as a single series of muscles, and thus are not homologous with muscles of the same name in Lepidosauria or Crocodylia. The avian mm. inclusi that lie medial to mm. intertransversarii are homologous with mm. intercostales externi in Lepidosauria and mm. intercostales externi and m. scalenus combined in Crocodylia. Innervation patterns suggest that a muscle (“m. iliocostalis capitis”) connecting the atlas rib and occiput in Crocodylia includes contributions from the subvertebral layer and m. cucullaris complex, and possibly m. iliocostalis as well. The present findings may serve as a basis for revising the currently used avian nomenclature so that it will reflect homologies of muscles with their non‐avian counterparts. J.
