thyroglossal duct in dogs

An embryological anatomical structure that forms an open connection between the initial area of development of the thyroid gland and its final position; it is located exactly midline, between the anterior 2/3rds and posterior 1/3rd of the tongue; this duct normally atrophies and closes off as the foramen cecum before birth. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the thyroglossal duct is

An embryological anatomical structure that forms an open connection between the initial area of development of the thyroid gland and its final position; it is located exactly midline, between the anterior 2/3rds and posterior 1/3rd of the tongue; this duct normally atrophies and closes off as the foramen cecum before birth. The atlas records it as a organ at the organ scale in the dog.

Where the thyroglossal duct is

It sits within the endocrine 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 thyroglossal duct connects to

The atlas records 3 typed relationships for it, across 2 kinds of connection. part of multicellular organism and thyroid gland.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the thyroglossal duct. 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 ductus thyroglossus and ductus thyroglossalis. Searching any of those names reaches this page.

Questions

Where is the thyroglossal duct?

It sits within the endocrine 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 thyroglossal duct connect to?

Part of: multicellular organism and thyroid gland.

Is the thyroglossal duct 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.
