main ciliary ganglion

A parasympathetic ganglion located in the posterior orbit that contains preganglionic nerves and postganglionic neurons of the oculomotor nerve, connects to the Edinger-Westphal nucleus via the oculomotor nerve and the eye muscles via the short ciliary nerve. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the main ciliary ganglion is

A parasympathetic ganglion located in the posterior orbit that contains preganglionic nerves and postganglionic neurons of the oculomotor nerve, connects to the Edinger-Westphal nucleus via the oculomotor nerve and the eye muscles via the short ciliary nerve. The atlas records it as a nerve at the organ scale in the human body.

Where the main ciliary ganglion is

It sits in the head, within the nervous 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 main ciliary ganglion connects to

The atlas records 6 typed relationships for it, across 4 kinds of connection. part of ocular adnexa and orbital region.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the main ciliary ganglion. 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 ciliary ganglion and ganglion ciliare. Searching any of those names reaches this page.

Questions

Where is the main ciliary ganglion?

It sits in the head, within the nervous 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 main ciliary ganglion connect to?

Part of: ocular adnexa and orbital region.

Is the main ciliary ganglion 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.
