In biology, a tagma (Greek: τάγμα, pl.: tagmata – τάγματα - body of soldiers; battalion) is a specialized grouping of multiple segments or metameres into a coherently functional morphological unit.

2022年8月24日 · The segmentation of Arthropod bodies is different from that of Annelids in that they consist of subsections composed of fused segments referred to as tagmatization. Tagmata are the specific sections (i.e. Head, Thorax, Abdomen), which may vary from species to species.

The meaning of TAGMA is a compound body section of an arthropod resulting from embryonic fusion of two or more somites (as the cephalothorax of a spider) or consisting of two or more distinguishable segments (as the thorax of an insect).

2013年8月5日 · The tagma (Greek: τάγμα, pl. tagmata) is a term for a military unit of battalion or regiment size. The best-known and most technical use of the term however refers to the elite regiments formed by Byzantine Emperor Constantine V and comprising the central army of the Byzantine Empire in the 8th–11th centuries.

Tagmatization is the evolutionary process by which the body of an organism becomes divided into specialized segments or regions, known as tagmata, that perform distinct functions.

2025年2月10日 · Tagmosis is the process by which an organism's body becomes divided into distinct regions or segments. In insects, this process is unique in that it divides the body into three main tagmata: head, thorax, and abdomen.

2018年5月29日 · tagma (pl. tagmata) A section of the body of an arthropod that is formed by the fusion of mesodermal somites and has a distinct function and structure. The basic tagmata are the head, thorax, and abdomen, but the form of the tagmata (known as tagmosis) varies between arthropod groups, each group having its characteristic tagmosis.

Tagma (from Greek τάγμα "something which has been ordered or arranged"; plural tagmata) may refer to: Tagma (biology), a grouping of segments, usually in arthropod anatomy; Tagma (military), a subdivision of the Byzantine army; Tagma (τάγμα), the Modern Greek term for an order (honour) Moha Tagma (born 1954), Moroccan diplomat

While the nature and composition of the tagmata vary among arthropod classes, they 34 are more or less conserved at the level of the class, and are often used as defining characters of 35 the class.
