前言：比目鱼肌(SM)与腓肠肌(GM)、足底肌同位于小腿浅后间隙。关于SM的形态变异性(羽化)的信息很少。本研究的目的是描述SM喙的形态变化，并建立第一个准确的分类。材料和方法：80条肢体(左40条，右40条)在10%福尔马林溶液中固定。结果：所有病例均有比目鱼肌的存在。根据肌纤维形态可分为四种类型。按出现频率排序：类型1-二年生(43.75%)；类型4-非一年生(36.25%)；类型2-一年生(15%)；类型3-多年生(5%)。不同体侧(p=0.9018)和不同性别(p=0.0844)的比目鱼肌类型分布无显著差异。根据羽状角，比目鱼肌分为四种类型(1-4)。(C)2020爱思唯尔股份有限公司。版权所有。
Introduction: The soleus muscle (SM) is located in the superficial posterior compartment of the leg, together with the gastrocnemius muscle (GM) and plantaris muscle. There is little information on the morphological variability (pennation) of the SM. The aim of the study is to characterize the variations in the morphology of the pennation of the SM and to create the first accurate classification.Material and methods: Eighty lower limbs (40 left, and 40 right) fixed in 10% formalin solution were examined. The morphology of the central tendon, medial and lateral aponeuroses was evaluated, together with the pennation angle.Results: In all cases, the soleus muscle was present. Four types could be distinguished based on muscle fibre morphology. In order of frequency: Type 1 - bipennate (43.75%); Type 4 - non-pennate (36.25%); Type 2 - unipennate (15%); Type 3 - multipennate (5%). No significant difference in type distribution was observed with regard to body side (p =0.9018) or gender (p =0.0844).Conclusion: The soleus muscle is characterized by high morphological variability. Based on the pennation angle, four types (1-4) of soleus muscle are distinguishable. (C) 2020 Elsevier GmbH. All rights reserved.
