Also called metamere
Example sentencesExamples
- The trunk section, the perion, consists of the remainder of the typical thoracic somites.
- 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 neural tube of the body tends to segment in an orderly way along the boundaries between somites.
- The basis for the confusion arises from the visible suture between somites 4 and 5, which suggests that the fusion is not complete.
- This takes the vertebrate embryo up to the stage at which it has become recognizably vertebrate, with somites, notochord, and neural tube.

Origin

Mid 19th century: from Greek sōma 'body' + -ite¹.
