2020年8月17日 · 综荐骨 （英语： synsacrum）是鸟类和非鸟恐龙的一个骨骼。 在这种结构中，荐骨通过并入另外愈合或部分愈合的尾椎或腰椎而延伸。 一些后部的胸椎、腰椎椎骨，骶骨和一些前部的尾椎椎骨融合在一起，形成了综荐骨这个复杂的结构。 根据物种的不同，骶骨或多或少与综荐骨融合在一起，形成了禽类骨盆。 这形成了比哺乳动物的骨盆更广泛的刚性结构，满足了飞行、运动和呼吸的要求。 综荐骨后部有一些游离的尾椎骨，它们最后一个叫尾综骨，上面长有坚硬 …

愈合荐骨(综荐骨)(synsacrum)是鸟类特有的结构。 它是由 少数胸椎、腰椎、荐椎以及一部分尾椎 愈合而成的，而且它又与宽大的 骨盘(髂骨、坐骨与耻骨) 相愈合，使鸟类在地面步行时获得支持体重的坚实支架。

The synsacrum is an avian skeletal structure formed by fusion of the sacrum with a variable number of lumbar and caudal (coccygeal) vertebrae (see Landscape Fig. 6.0-7). This fusion of vertebral elements is an adaptation for flight and locomotion in birds.

The synsacrum is a composite bony structure found in birds, formed by the fusion of several vertebrae from the lumbar, sacral, and sometimes thoracic regions. This unique adaptation provides increased rigidity and support to the bird's body, which is essential for flight.
