epithelium

Portion of tissue, that consists of one or more layers of epithelial cells connected to each other by cell junctions and which is underlain by a basal lamina. Examples: simple squamous epithelium, glandular cuboidal epithelium, transitional epithelium, myoepithelium[CARO]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the epithelium is

Portion of tissue, that consists of one or more layers of epithelial cells connected to each other by cell junctions and which is underlain by a basal lamina. Examples: simple squamous epithelium, glandular cuboidal epithelium, transitional epithelium, myoepithelium[CARO]. The atlas records it as a tissue at the tissue scale in the human body.

Where the epithelium is

This dataset records no region or system for it. No positional evidence of any kind. Drawn outside the body so it can still be found and counted, never inside it.

What the epithelium connects to

The atlas records 126 typed relationships for it, across 6 kinds of connection. part of mucosa and respiratory tube.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the epithelium. 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 epithelial tissue and portion of epithelium. Searching any of those names reaches this page.

Questions

Where is the epithelium?

This dataset records no region or system for it. No positional evidence of any kind. Drawn outside the body so it can still be found and counted, never inside it.

What does the epithelium connect to?

Part of: mucosa and respiratory tube.

Is the epithelium 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.
