头骨是由许多骨头组成的，这些骨头在骨缝处结合在一起。这些缝线是重要的生长部位，当生长停止时，一些缝线融合，而另一些缝线保持开放。它们的机械行为以及它们如何与变化的形式和负载相互作用以确保平衡的颅面发育仍然知之甚少。早期缝线融合往往会导致毁容综合症，因此我们必须更清楚地了解缝线的功能。通过应用先进的工程建模技术，我们首次揭示了专利缝线在整个爬行动物头骨中产生更广泛分布的高水平应变。如果没有通畅的缝合线，颅骨的大部分区域只会受到罕见的低水平应变，这可能会削弱骨骼并导致异常发育。因此，缝不仅是骨骼生长的场所，而且对于调节爬行动物正常生长和发育所需的应变也是必不可少的。
The skull is composed of many bones that come together at sutures. These sutures are important sites of growth, and as growth ceases some become fused while others remain patent. Their mechanical behaviour and how they interact with changing form and loadings to ensure balanced craniofacial development is still poorly understood. Early suture fusion often leads to disfiguring syndromes, thus is it imperative that we understand the function of sutures more clearly. By applying advanced engineering modelling techniques, we reveal for the first time that patent sutures generate a more widely distributed, high level of strain throughout the reptile skull. Without patent sutures, large regions of the skull are only subjected to infrequent low-level strains that could weaken the bone and result in abnormal development. Sutures are therefore not only sites of bone growth, but could also be essential for the modulation of strains necessary for normal growth and development in reptiles.
