Abstract：
In comparative anatomy, the adductor muscles are said to be quite variable and to often cause difficulty in separation. The arrangement of these muscles and the possible occurrence of the adductor minimus and obturator intermedius muscles in the albino rat has not been investigated. The aim of this study was to accurately describe the adductor muscles in the albino rat (Rattus norvegicus). We hypothesized that all adductor muscles are constantly present and can be separated in a constant manner, and that the adductor minimus and obturator intermedius muscles are constant structures. Both pelvic limbs of 30 formalin-embalmed male albino rats were carefully dissected. The identification of the individual muscles was made based on their position in relation to the two branches of the obturator nerve and by comparing our results with previous findings in other species including humans. All examined rats had two gracilis muscles. The adductor longus muscle was the most superficial and smallest individual. The adductor brevis split into two parts of insertion-the femoral and genicular parts. The adductor magnus and minimus muscles could be separated constantly. The obturator intermedius muscle was a constant structure next to the obturator externus muscle. The adductor muscles of the albino rat were constantly separable and could be clearly assigned to their names. Further research is needed to investigate these muscles, especially the obturator intermedius muscle, in other species including humans.
摘要：
在比较解剖学中，内收肌据说是相当可变的，并且经常导致分离困难。尚未研究这些肌肉的排列以及白化病大鼠中内收肌和闭孔中间肌的可能发生。这项研究的目的是准确描述白化病大鼠（Rattusnorvegicus）的内收肌。我们假设所有内收肌都是持续存在的，并且可以以恒定的方式分离，内收肌和闭孔肌是恒定的结构。仔细解剖30只福尔马林防腐的雄性白化病大鼠的两个骨盆肢体。个体肌肉的识别是根据它们相对于闭孔神经的两个分支的位置，并将我们的结果与包括人类在内的其他物种的先前发现进行比较。所有被检查的大鼠都有两条股薄肌肉。内收肌是最浅层和最小的个体。短收肌分为两个插入部分-股骨和膝部。内收肌和小肌可以不断分离。闭孔中间肌是闭孔外部肌旁边的恒定结构。白化病大鼠的内收肌是不断可分离的，可以清楚地指定它们的名字。需要进一步的研究来研究这些肌肉，尤其是闭孔中间肌，包括人类在内的其他物种。
