sclera

Opaque fibrous outer layer of the eyeball[ZFA,Kardong,WP]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the sclera is

Opaque fibrous outer layer of the eyeball[ZFA,Kardong,WP]. The atlas records it as a organ at the organ scale in the human body.

Where the sclera is

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

What the sclera connects to

The atlas records 12 typed relationships for it, across 7 kinds of connection. part of tunica fibrosa of eyeball.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the sclera. 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 scleral capsule. Searching any of those names reaches this page.

Questions

Where is the sclera?

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

What does the sclera connect to?

Part of: tunica fibrosa of eyeball.

Is the sclera 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.
