取经10％福尔马林固定后,又经25％醋酸处理过的指浅、深屈肌腱15对,拇长屈肌腱和(足母)长屈肌腱各5对,作了肉眼解剖观察和组织切片观察。手的指浅屈肌腱初位于指深屈肌腱的掌侧,进而分劈为两半,围绕指深屈肌腱的侧面再转到它的背面。指深屈肌腱的形态变化与指浅屈肌腱分裂所形成的隧道相适应。指深屈肌腱纤维束的排列呈螺旋形扭转。拇((足母))长屈肌腱纤维的排列与指深屈肌腱的相似,这似能进一步论证两者在进化上的同源关系。在拇((足母))长屈肌腱的两侧均有较明显的侧束。而腱形态上的改变是由于腱纤维束排列上的变化所致。本文所见腱纤维束的扭转和交织,提示它使腱更为坚韧,也便于肌力的传递。一般说来,腱的坚韧程度与腱纤维的排列方式有关,而其肌肉的作用力又和腱的强弱有关。本文还讨论了“穿肌腱”的来源问题。
Fifteen pairs of finger and shallow flexor tendon, five pairs of flexor hallucis longus and five flexor hallucis longus tendon were obtained after fixation with 10% formalin, and then treated with 25% acetic acid for visual observation. Slice observation. The superficial flexor tendon of the hand is initially located on the palmar side of the tendon of the deep flexor tendon, splitting it in half, and then turning to the back of the side of the tendon, which refers to the deep flexor tendon. Refers to the morphological changes of deep flexor tendon and superficial flexor tendon split formed by the tunnel adapted. Refers to the arrangement of deep flexor tendon fiber bundles twisted spiral. The thumb ((foot)) long flexor tendon fibers arranged with the tendons of the deep flexor tendon, which may further demonstrate the evolutionary homology between the two. In the thumb ((foot)) flexor tendons tendon on both sides of the more obvious side beam. The change in tendon morphology is due to changes in the tendon fiber bundle arrangement. Torsion and intertwining of the tendon fibers seen in this article suggest that it makes the tendon more tenacious and facilitates the transfer of muscle strength. In general, the tenacity of the tendon is related to the arrangement of the tendon fibers, and its muscle force is related to the strength of the tendon. This article also discusses the source of “wear tendons.”
