hypothalamus in dogs

A specialized brain region of the ventral diencephalon arising near the end of the segmentation period; the embryonic hypothalamic region will give rise to the posterior pituitary gland as well as a number of brain nuclei. [ZFA]. One of the most important functions of the hypothalamus is to link the nervous system to the endocrine system via the pituitary gland (hypophysis).[Wikipedia]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the hypothalamus is

A specialized brain region of the ventral diencephalon arising near the end of the segmentation period; the embryonic hypothalamic region will give rise to the posterior pituitary gland as well as a number of brain nuclei. [ZFA]. One of the most important functions of the hypothalamus is to link the nervous system to the endocrine system via the pituitary gland (hypophysis).[Wikipedia]. The atlas records it as a nerve at the organ scale in the dog.

Where the hypothalamus 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 hypothalamus connects to

The atlas records 29 typed relationships for it, across 5 kinds of connection. part of anatomical entity, brain and diencephalon, and 3 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the hypothalamus. 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 Hy, preoptico-hypothalamic area, preoptico-hypothalamic region and hypothalamus. Searching any of those names reaches this page.

Questions

Where is the hypothalamus?

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 hypothalamus connect to?

Part of: anatomical entity, brain, diencephalon, forebrain, limbic system and nervous system.

Is the hypothalamus 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.
