red nucleus

Large round nucleus located in the midbrain tegmentum, consisting of a magnocellular and parvicellular portion in most species studied. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the red nucleus is

Large round nucleus located in the midbrain tegmentum, consisting of a magnocellular and parvicellular portion in most species studied. The atlas records it as a nerve at the organ scale in the human body.

Where the red nucleus 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 red nucleus connects to

The atlas records 8 typed relationships for it, across 3 kinds of connection. part of brainstem, midbrain and midbrain tegmentum.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the red nucleus. 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 R, nucleus ruber, nucleus rotundus subthalamo-peduncularis, nucleus ruber tegmenti, nucleus ruber tegmenti (Stilling) and red nucleus (Burdach). Searching any of those names reaches this page.

Questions

Where is the red nucleus?

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 red nucleus connect to?

Part of: brainstem, midbrain and midbrain tegmentum.

Is the red nucleus 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.
