ventral thalamus in dogs

Anterior part of the diencephalon that lies between the dorsal thalamus, hypothalamus, and tegmentum of the mesencephalon, including subthalamic nucleus, zona incerta, the fields of Forel, and the nucleus of ansa lenticularis[GO, modified]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the ventral thalamus is

Anterior part of the diencephalon that lies between the dorsal thalamus, hypothalamus, and tegmentum of the mesencephalon, including subthalamic nucleus, zona incerta, the fields of Forel, and the nucleus of ansa lenticularis[GO, modified]. The atlas records it as a nerve at the organ scale in the dog.

Where the ventral thalamus 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 ventral thalamus connects to

The atlas records 13 typed relationships for it, across 5 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 ventral thalamus. 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 SbTh, subthalamic region, subthalamus, thalamus ventralis, ventral thalamus and perithalamus, and 1 more. Searching any of those names reaches this page.

Questions

Where is the ventral thalamus?

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 ventral thalamus connect to?

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

Is the ventral thalamus 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.
