lens placode

A thickened portion of ectoderm which serves as the precursor to the lens. SOX2 and Pou2f1 are involved in its development[WP]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the lens placode is

A thickened portion of ectoderm which serves as the precursor to the lens. SOX2 and Pou2f1 are involved in its development[WP]. The atlas records it as a region at the region scale in the human body.

Where the lens placode is

It sits in the head. 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 lens placode connects to

The atlas records 8 typed relationships for it, across 3 kinds of connection. part of craniocervical region, ectoderm and embryo, and 1 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the lens placode. 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 lens placodes and placoda lentis. Searching any of those names reaches this page.

Questions

Where is the lens placode?

It sits in the head. 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 lens placode connect to?

Part of: craniocervical region, ectoderm, embryo and head.

Is the lens placode 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.
