Preferred Label : zygomatic plate;
Uberon definition : In rodent anatomy, the zygomatic plate is a bony plate derived from the flattened
front part of the zygomatic arch (cheekbone). At the back, it connects to the front
(maxillary) root of the zygomatic arch, and at the top it is connected to the rest
of the skull via the antorbital bridge. It is part of the maxillary bone, or upper
jaw, which also contains the upper cheekteeth. Primitively, rodents have a nearly
horizontal zygomatic plate. In association with specializations in zygomasseteric
system, several distinct morphologies have developed across the order. The term is
also used for an analogous structure in some South American typotheres, including
Pseudotypotherium and Medistylus.;
