ventral thalamus

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 human body.

Where the ventral thalamus is

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

What the ventral thalamus connects to

The atlas records 17 typed relationships for it, across 6 kinds of connection. part of dorsal plus ventral thalamus.

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.

Questions

Where is the ventral thalamus?

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

What does the ventral thalamus connect to?

Part of: dorsal plus ventral thalamus.

Is the ventral thalamus 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.
