thyroid follicle

Discrete, cystlike units of the thyroid gland that are lined with cuboidal epithelium and are filled with a colloid substance, about 30 to each lobule[BTO]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the thyroid follicle is

Discrete, cystlike units of the thyroid gland that are lined with cuboidal epithelium and are filled with a colloid substance, about 30 to each lobule[BTO]. The atlas records it as a organ at the organ scale in the human body.

Where the thyroid follicle 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 thyroid follicle connects to

The atlas records 6 typed relationships for it, across 4 kinds of connection. part of thyroid gland.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the thyroid follicle. 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 thyroid gland follicle and thyroid follicles. Searching any of those names reaches this page.

Questions

Where is the thyroid follicle?

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 thyroid follicle connect to?

Part of: thyroid gland.

Is the thyroid follicle 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.
