supraoptic nucleus in dogs

The supraoptic nucleus (SON) is a nucleus of magnocellular neurosecretory cells in the hypothalamus of the mammalian brain. The nucleus is situated at the base of the brain, adjacent to the optic chiasm. [WP,unvetted]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the supraoptic nucleus is

The supraoptic nucleus (SON) is a nucleus of magnocellular neurosecretory cells in the hypothalamus of the mammalian brain. The nucleus is situated at the base of the brain, adjacent to the optic chiasm. [WP,unvetted]. The atlas records it as a nerve at the organ scale in the dog.

Where the supraoptic nucleus 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 supraoptic nucleus connects to

The atlas records 8 typed relationships for it, across 3 kinds of connection. part of anatomical entity, brain and hypothalamus, and 2 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the supraoptic 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 SO, nucleus supraopticus, supra-optic nucleus, supraoptic nucleus of hypothalamus, nucleus supraopticus hypothalami and nucleus tangentialis (Riley), and 3 more. Searching any of those names reaches this page.

Questions

Where is the supraoptic nucleus?

What does the supraoptic nucleus connect to?

Part of: anatomical entity, brain, hypothalamus, nervous system and periventricular zone of hypothalamus.

Is the supraoptic nucleus 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.
