epithalamus in dogs

Most dorsal part of the thalamus, comprising the pineal gland and habenular nuclei in most vertebrates. In a few vertebrates, it also includes the parietal eye. (Butler and Hodos, Comparative Vertebrate Neuroanatomy, 2nd ed, 2005, pg. 345-346. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the epithalamus is

Most dorsal part of the thalamus, comprising the pineal gland and habenular nuclei in most vertebrates. In a few vertebrates, it also includes the parietal eye. (Butler and Hodos, Comparative Vertebrate Neuroanatomy, 2nd ed, 2005, pg. 345-346. The atlas records it as a nerve at the organ scale in the dog.

Where the epithalamus 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 epithalamus connects to

The atlas records 10 typed relationships for it, across 4 kinds of connection. part of anatomical entity, brain and dorsal plus ventral thalamus, and 1 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the epithalamus. 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 ETh and epithalamus. Searching any of those names reaches this page.

Questions

Where is the epithalamus?

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 epithalamus connect to?

Part of: anatomical entity, brain, dorsal plus ventral thalamus and nervous system.

Is the epithalamus 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.
