suprachiasmatic nucleus in dogs

* An ovoid densely packed collection of small cells of the anterior hypothalamus lying close to the midline in a shallow impression of the optic chiasm. (MSH) * small group of nerve cell bodies in the supraoptic region of the hypothalamus, just above the optic chiasm; influences rhythmic aspects of hypothalamic functions in many vertebrate species. (CSP). Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the suprachiasmatic nucleus is

* An ovoid densely packed collection of small cells of the anterior hypothalamus lying close to the midline in a shallow impression of the optic chiasm. (MSH) * small group of nerve cell bodies in the supraoptic region of the hypothalamus, just above the optic chiasm; influences rhythmic aspects of hypothalamic functions in many vertebrate species. (CSP). The atlas records it as a nerve at the organ scale in the dog.

Where the suprachiasmatic 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 suprachiasmatic nucleus connects to

The atlas records 6 typed relationships for it, across 3 kinds of connection. part of diencephalon, medial zone of hypothalamus and preoptic area.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the suprachiasmatic 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 SCN, SCh, suprachiasmatic nucleus of hypothalamus, nucleus suprachiasmaticus, nucleus suprachiasmaticus hypothalami and suprachiasmatic nucleus (Spiegel-Zwieg). Searching any of those names reaches this page.

Questions

Where is the suprachiasmatic nucleus?

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 suprachiasmatic nucleus connect to?

Part of: diencephalon, medial zone of hypothalamus and preoptic area.

Is the suprachiasmatic 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.
