habenula in dogs

A segment of the epithalamus that has as its parts the habenular nuclei and the habenular commissure[FMA,modified]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the habenula is

A segment of the epithalamus that has as its parts the habenular nuclei and the habenular commissure[FMA,modified]. The atlas records it as a nerve at the organ scale in the dog.

Where the habenula 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 habenula connects to

The atlas records 9 typed relationships for it, across 4 kinds of connection. part of anatomical entity, brain and epithalamus, and 1 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the habenula. 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 Hb, habenula complex, ganglion intercrurale, ganglion interpedunculare, habenulae and habenular complex, and 4 more. Searching any of those names reaches this page.

Questions

Where is the habenula?

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 habenula connect to?

Part of: anatomical entity, brain, epithalamus and nervous system.

Is the habenula the same in other species?

This page describes the dog. The human record of the same structure sits beside it on /compare, over one shared model rather than two atlases built separately.
