preoptic area

Area of the forebrain between the anterior commissure and optic chiasm. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the preoptic area is

Area of the forebrain between the anterior commissure and optic chiasm. The atlas records it as a nerve at the organ scale in the human body.

Where the preoptic area 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 preoptic area connects to

The atlas records 8 typed relationships for it, across 3 kinds of connection. part of diencephalon.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the preoptic area. 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 POA, preoptic nuclei, preoptic region of hypothalamus, area hypothalamica rostralis, area praeoptica and area preoptica, and 5 more. Searching any of those names reaches this page.

Questions

Where is the preoptic area?

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 preoptic area connect to?

Part of: diencephalon.

Is the preoptic area 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.
