splenic cord in dogs

A structure found in the red pulp of the spleen between the sinusoids, consisting of fibrils and connective tissue cells with a large population of monocytes and macrophages. These cords contain half of the human body's monocytes as a reserve so that after tissue injury these monocytes can move in and aid locally sourced monocytes in wound healing. Erythrocytes pass through the cords of Billroth before entering the sinusoids. The passage into the sinusoids may be seen as a bottleneck, where erythrocytes need to be flexible in order to pass through. In disorders of erythrocyte shape and/or flexibility, such as hereditary spherocytosis, erythrocytes fail to pass through and get phagocytosed, causing extravascular hemolysis. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the splenic cord is

A structure found in the red pulp of the spleen between the sinusoids, consisting of fibrils and connective tissue cells with a large population of monocytes and macrophages.

In disorders of erythrocyte shape and/or flexibility, such as hereditary spherocytosis, erythrocytes fail to pass through and get phagocytosed, causing extravascular hemolysis. The atlas records it as a organ at the organ scale in the dog.

Where the splenic cord is

It sits in the abdomen and trunk, within the lymphatic & immune system. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.

What the splenic cord connects to

The atlas records 3 typed relationships for it, across 2 kinds of connection. part of organ and red pulp of spleen.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the splenic cord. 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 cord of Billroth and cord of Bilroth. Searching any of those names reaches this page.
