subthalamic nucleus

The subthalamic nucleus is the lens-shaped nucleus located in the ventral part of the subthalamus on the inner aspect of the internal capsule that is concerned with the integration of somatic motor function[GO]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the subthalamic nucleus is

The subthalamic nucleus is the lens-shaped nucleus located in the ventral part of the subthalamus on the inner aspect of the internal capsule that is concerned with the integration of somatic motor function[GO]. The atlas records it as a nerve at the organ scale in the human body.

Where the subthalamic nucleus is

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

What the subthalamic nucleus connects to

The atlas records 6 typed relationships for it, across 4 kinds of connection. part of dorsal thalamus, ventral nuclear group and ventral thalamus.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the subthalamic nucleus. 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 Luys' nucleus, body of Forel, body of Luys, nucleus of Luys, nucleus of corpus luysii and nucleus subthalamicus, and 6 more. Searching any of those names reaches this page.

Questions

Where is the subthalamic nucleus?

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

What does the subthalamic nucleus connect to?

Part of: dorsal thalamus, ventral nuclear group and ventral thalamus.

Is the subthalamic nucleus 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.
