corpora quadrigemina

Either of the two pairs of colliculi on the dorsal surface of the midbrain composed of white matter externally and gray matter within, the superior pair containing correlation centers for optic reflexes and the inferior pair containing correlation centers for auditory reflexes[BTO]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the corpora quadrigemina is

Either of the two pairs of colliculi on the dorsal surface of the midbrain composed of white matter externally and gray matter within, the superior pair containing correlation centers for optic reflexes and the inferior pair containing correlation centers for auditory reflexes[BTO]. The atlas records it as a organ at the organ scale in the human body.

Where the corpora quadrigemina is

It sits 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 corpora quadrigemina connects to

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

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the corpora quadrigemina. 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 colliculi, corpora quadrigemina, quadrigeminal body and set of colliculi. Searching any of those names reaches this page.

Questions

Where is the corpora quadrigemina?

It sits 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 corpora quadrigemina connect to?

Part of: midbrain tectum.

Is the corpora quadrigemina 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.
