pupil

The central circular aperture of the iris through which light rays enter the eye. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the pupil is

The central circular aperture of the iris through which light rays enter the eye. The atlas records it as a cavity at the organ scale in the human body.

Where the pupil is

It sits in the head, within the sensory system. Positioned deliberately as part of this species body plan.

What the pupil connects to

The atlas records 6 typed relationships for it, across 5 kinds of connection. part of iris.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the pupil. 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.

Questions

Where is the pupil?

It sits in the head, within the sensory system. Positioned deliberately as part of this species body plan.

What does the pupil connect to?

Part of: iris.

Is the pupil 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.
