Zygomatic arch



the bony arch at the outer border of the eye socket, formed by the union of the cheekbone and the zygomatic process of the temporal bone.
Historical Examples

The cranial cavity is very small, the orbit confluent with the temporal fossa, and the zygomatic arch massive.
The Vertebrate Skeleton Sidney H. Reynolds

In Ornithorhynchus the zygomatic arch is much stouter than in Echidna.
The Vertebrate Skeleton Sidney H. Reynolds

As yet there is no clear evidence that reduction of the zygomatic arch is of adaptive value.
Natural History of the Ornate Box Turtle, Terrapene ornata ornata Agassiz John M. Legler

The orbit is not encircled by bone, but there is a strong process from the frontal, which nearly meets the zygomatic arch.
The Cambridge Natural History, Vol X., Mammalia Frank Evers Beddard

The zygomatic arch is slender, and postorbital processes are not generally well developed.
The Vertebrate Skeleton Sidney H. Reynolds

The zygomatic arch is complete, but the jugal is short and only forms the middle of it.
The Vertebrate Skeleton Sidney H. Reynolds

Processes from the jugal and frontal in living forms never meet and enclose the orbit, but the zygomatic arch is always complete.
The Vertebrate Skeleton Sidney H. Reynolds

The zygomatic arch is occasionally fractured by a direct blow.
Manual of Surgery Volume Second: Extremities–Head–Neck. Sixth Edition. Alexander Miles

The zygomatic arch is usually slender or incomplete, and the coronoid process and angle of the mandible are commonly prominent.
The Vertebrate Skeleton Sidney H. Reynolds

The zygomatic arch is incomplete, and the jugal (fig. 91, 5) is curiously forked, but in a manner differing in the two genera.
The Vertebrate Skeleton Sidney H. Reynolds
