head kidney in dogs

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 dog.

Where the head kidney is

It sits in the abdomen and trunk, within the endocrine and urinary systems. Only the region is known. The position shown is somewhere plausible inside it and nothing more.

What the head kidney connects to

The atlas records 9 typed relationships for it, across 4 kinds of connection. part of endocrine system, hematopoietic system and kidney.

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.
