conjunctiva

The mucous membrane that lines the inner surface of the eyelids and the front of the eyeball. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the conjunctiva is

The mucous membrane that lines the inner surface of the eyelids and the front of the eyeball. The atlas records it as a organ at the organ scale in the human body.

Where the conjunctiva is

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

What the conjunctiva connects to

The atlas records 14 typed relationships for it, across 6 kinds of connection. part of camera-type eye and conjunctival sac.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the conjunctiva. 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 conjunctivae, conjunctivas, tunica conjunctiva and wall of conjunctival sac. Searching any of those names reaches this page.

Questions

Where is the conjunctiva?

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

What does the conjunctiva connect to?

Part of: camera-type eye and conjunctival sac.

Is the conjunctiva 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.
