The jugal bone [arcus zygomaticus]

The jugal bone — or rather the place on the skull identified by this name — consists of two bony processes meeting each other at an oblique suture. The posterior part of it (X in figs. 3 and 5, ch. 6) is a process [processus zygomaticus] of the temporal bone; the anterior (V in the same figures) is considered a process [processus temporalis] of that bone [os zygomaticum] which forms the entire outside corner of the eye socket [orbita] and will be counted the first of the bones of the upper maxilla. Accordingly the jugal bone does not have its own ends and is nothing but a region of two processes joined to each other by a suture (Z in fig. 3, ch. 6) [sutura temporozygomatica].
