ciliary muscle

The ciliary muscle is a ring of smooth muscle in the middle layer of the eye that controls the eye's accommodation for viewing objects at varying distances and regulates the flow of aqueous humour through Schlemm's canal. [WP,unvetted]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the ciliary muscle is

The ciliary muscle is a ring of smooth muscle in the middle layer of the eye that controls the eye's accommodation for viewing objects at varying distances and regulates the flow of aqueous humour through Schlemm's canal. [WP,unvetted]. The atlas records it as a muscle at the organ scale in the human body.

Where the ciliary muscle is

It sits in the head, within the muscular and sensory systems. 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 ciliary muscle connects to

The atlas records 7 typed relationships for it, across 3 kinds of connection. part of camera-type eye and ciliary body.

Supply and innervation

Innervation: long ciliary nerve and short ciliary nerve.

Also called

Also recorded as musculus ciliarus, Bowman`s muscles, ciliaris and musculus ciliaris. Searching any of those names reaches this page.

Questions

Where is the ciliary muscle?

What does the ciliary muscle connect to?

Part of: camera-type eye and ciliary body.

Is the ciliary muscle 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.
