mesentery in dogs

Anatomical organ component composed of a double layer of serous membrane that suspends a viscus from the body wall or connects adjacent viscera and in doing so conveys blood vessels, lymphatics and nerves to and from the viscera. Examples: greater omentum, broad ligament of uterus, sigmoid mesocolon. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the mesentery is

Anatomical organ component composed of a double layer of serous membrane that suspends a viscus from the body wall or connects adjacent viscera and in doing so conveys blood vessels, lymphatics and nerves to and from the viscera. Examples: greater omentum, broad ligament of uterus, sigmoid mesocolon. The atlas records it as a tissue at the tissue scale in the dog.

Where the mesentery is

This dataset records no region or system for it. No positional evidence of any kind. Drawn outside the body so it can still be found and counted, never inside it.

What the mesentery connects to

The atlas records 17 typed relationships for it, across 4 kinds of connection. a kind of serous membrane.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the mesentery. 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 generic mesentery and mesentery (generic). Searching any of those names reaches this page.

Questions

Where is the mesentery?

This dataset records no region or system for it. No positional evidence of any kind. Drawn outside the body so it can still be found and counted, never inside it.

What does the mesentery connect to?

A kind of: serous membrane.

Is the mesentery the same in other species?

This page describes the dog. The human record of the same structure sits beside it on /compare, over one shared model rather than two atlases built separately.
