单词	somite
释义	somite /ˈsəʊmʌɪt / noun Zoology Each of a number of body segments containing the same internal structures, clearly visible in invertebrates such as earthworms but also present in the embryonic stages of vertebrates. Also called metamere.This takes the vertebrate embryo up to the stage at which it has become recognizably vertebrate, with somites, notochord, and neural tube.... If male abdomina are preserved, the fusion of the somites is also diagnostic; pseudoziids exhibit no fusion of somites while carpiliids have somites 3-5 fused. The basis for the confusion arises from the visible suture between somites 4 and 5, which suggests that the fusion is not complete. Origin Mid 19th century: from Greek sōma 'body' + -ite1.
