From their mode of attachment and their elastic composition, it is clear that the vincula of the chick serve other functions besides that of carrying blood vessels to the digital flexor tendons within their synovial sheaths. Evidence is presented in support of the argument that elastic fibres bear the brunt of rapidly applied tensile forces and that the interweaving collagen fibres only become taut when the vincula are stretched to the limit and about to tear. Our hypothesis is that the collagen serves as a check-rein mechanism in an otherwise elastic structure.
从它们的附着方式和弹性组成来看，很明显，鸡的腱纽除了将血管输送到滑膜鞘内的指屈肌腱之外，还具有其他功能。有证据支持这样的观点，即弹性纤维承受快速施加的拉力的主要作用，并且只有当腱纽被拉伸到极限并即将撕裂时，交织的胶原纤维才会绷紧。我们的假设是，在其他方面为弹性结构的胶原起到了控制机制的作用。
