anterior segment of eyeball

Any of the parts of the eye that lie in front of, or ventral to, the lens (inclusive). Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the anterior segment of eyeball is

Any of the parts of the eye that lie in front of, or ventral to, the lens (inclusive). The atlas records it as a organ at the organ scale in the human body.

Where the anterior segment of eyeball is

It sits in the head, within the sensory 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 anterior segment of eyeball connects to

The atlas records 15 typed relationships for it, across 5 kinds of connection. part of eyeball of camera-type eye.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the anterior segment of eyeball. 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

Questions

Where is the anterior segment of eyeball?

It sits in the head, within the sensory 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 anterior segment of eyeball connect to?

Part of: eyeball of camera-type eye.

Is the anterior segment of eyeball 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.
