zygomatic arch

The bony arch in vertebrates that extends along the side or front of the skull beneath the eye socket and is formed by the temporal process of the zygomatic bone and the zygomatic process of the temporal bone. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the zygomatic arch is

The bony arch in vertebrates that extends along the side or front of the skull beneath the eye socket and is formed by the temporal process of the zygomatic bone and the zygomatic process of the temporal bone. The atlas records it as a bone at the organ scale in the human body.

Where the zygomatic arch is

It sits in the head, within the skeletal system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What the zygomatic arch connects to

The atlas records 12 typed relationships for it, across 5 kinds of connection. part of craniocervical region, facial skeleton and head, and 2 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the zygomatic arch. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Also called

Also recorded as zygoma and arcus zygomaticus. Searching any of those names reaches this page.

Questions

Where is the zygomatic arch?

It sits in the head, within the skeletal system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What does the zygomatic arch connect to?

Part of: craniocervical region, facial skeleton, head, material anatomical entity and neurocranium.

Is the zygomatic arch the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
