lens nucleus

The core of the crystalline lens, surrounded by the cortex. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the lens nucleus is

The core of the crystalline lens, surrounded by the cortex. The atlas records it as a organ at the organ scale in the human body.

Where the lens nucleus is

It sits in the head, within the sensory 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 lens nucleus connects to

The atlas records 5 typed relationships for it, across 4 kinds of connection. part of lens of camera-type eye.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the lens nucleus. 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 nucleus of lens. Searching any of those names reaches this page.

Questions

Where is the lens nucleus?

It sits in the head, within the sensory 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 lens nucleus connect to?

Part of: lens of camera-type eye.

Is the lens nucleus 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.
