head kidney

Teleost head kidney consists of fused bilateral lobes located in the anterior part of the kidney. It is analogous to the mammalian bone marrow and the primary site of definitive hematopoiesis[ZFA,modified]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the head kidney is

Teleost head kidney consists of fused bilateral lobes located in the anterior part of the kidney. It is analogous to the mammalian bone marrow and the primary site of definitive hematopoiesis[ZFA,modified]. The atlas records it as a organ at the organ scale in the human body.

Where the head kidney is

It sits in the abdomen and trunk, within the endocrine and urinary systems. 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 head kidney connects to

The atlas records 11 typed relationships for it, across 4 kinds of connection. part of abdomen, abdominal segment of trunk and endocrine system, and 2 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the head kidney. 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 anterior kidney and kidney marrow. Searching any of those names reaches this page.

Questions

Where is the head kidney?

It sits in the abdomen and trunk, within the endocrine and urinary systems. 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 head kidney connect to?

Part of: abdomen, abdominal segment of trunk, endocrine system, hematopoietic system and kidney.

Is the head kidney 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.
