corpus callosum

White matter structure containing massive numbers of commissural fibers connecting cortical areas in the two cerebral hemispheres. It is subdivided into a genu, a rostrum, a body, and a splenium. (MM). Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the corpus callosum is

White matter structure containing massive numbers of commissural fibers connecting cortical areas in the two cerebral hemispheres. It is subdivided into a genu, a rostrum, a body, and a splenium. (MM). The atlas records it as a nerve at the organ scale in the human body.

Where the corpus callosum is

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

What the corpus callosum connects to

The atlas records 14 typed relationships for it, across 5 kinds of connection. part of brain and telencephalon.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the corpus callosum. 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.

Questions

Where is the corpus callosum?

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

What does the corpus callosum connect to?

Part of: brain and telencephalon.

Is the corpus callosum 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.
