The mesosternum is a term used in anatomy to denote the middle ventral plate (sternite) of the thorax in many arthropods, especially insects. It corresponds to the sternite of the mesothorax, lying between the prosternum (anterior) and the metasternum (posterior).
In structure and function, the mesosternum forms a ventral shield that helps define the ventral boundary of
Taxonomic variation is common. In many beetles, flies, wasps, and other insects, the mesosternum shows species-
In contrast, the term mesosternum is not a standard feature of vertebrate anatomy. In humans and other
