Preferred Label : trunk mesoderm;
Uberon definition : The mesoderm of segments T1-A9. It first becomes morphologically distinct during ventral
furrow formation. Following invagination during stages 6 and 7, it remains a coherent
structure with no morphologically apparent subdivisions, apart from transient metamery
during stage 9, until stage 11. It undergoes a number of morphological changes during
this period: as its cells divide following invagination, it loses its epithelial integrity
and by stage 9 has rearranged into a monolayer of cuboidal cells. A further division
happens during stage 10 leading to two distinct layers by stage 11.;
