insula

Gray matter of the insular region of the neocortex. In gyrencephalic animals, it is part of the insular lobe and lies in the depths of the lateral fissure and covered by portions of the frontal, parietal and temporal lobes. It includes Brodmann areas 13-16. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the insula is

Gray matter of the insular region of the neocortex. In gyrencephalic animals, it is part of the insular lobe and lies in the depths of the lateral fissure and covered by portions of the frontal, parietal and temporal lobes. It includes Brodmann areas 13-16. The atlas records it as a nerve at the organ scale in the human body.

Where the insula is

It sits within the nervous system. Positioned deliberately as part of this species body plan.

What the insula connects to

The atlas records 6 typed relationships for it, across 3 kinds of connection. part of cerebral cortex and cerebral hemisphere.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the insula. 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 iNS, central lobe, cortex of island, insula lobule, insular lobe and insular region, and 10 more. Searching any of those names reaches this page.

Questions

Where is the insula?

It sits within the nervous system. Positioned deliberately as part of this species body plan.

What does the insula connect to?

Part of: cerebral cortex and cerebral hemisphere.

Is the insula 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.
