腿 (节肢动物) Arthropod leg(重定向自Jointed leg)
![]() ![]() ![]() ![]() 节肢动物的腿,是体节上的附属肢(简称附肢),通常用于行走。在英语中,节肢动物附属肢的许多术语源自于拉丁文,并且通常与用于描述骨头的术语相混淆。例如:coxa (底节或者髋关节)、trochanter(转节或者股骨端部隆起部位)、femur(股节或者股骨)、tibia(胫节或者胫骨)、tarsus(跗节或者跗骨)、ischium(坐节或者坐骨)、metatarsus(后跗节或者蹠骨)、carpus(腕节或者腕骨)、dactylus (指节或者手指)以及patella(膝节或者髌骨)等。 有关不同节肢动物直接的各个附肢关节的同源性很难考究,也是诸多争论的焦点。有些作者认为,现存节肢动物的最近共同祖先的附肢关节可以分成十一段,但是现代节肢动物则只有8节,甚至更少。同时也有讨论认为,节肢动物祖先也许不需要这幺复杂的附肢构造,然而由于其它事件,例如某个同位基因功能的连续丢失,同时导致了组关节的增加。
