mesentery

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 human body.

Where the mesentery is

This dataset records no region or system for it. Positioned deliberately as part of this species body plan.

What the mesentery connects to

The atlas records 14 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. Positioned deliberately as part of this species body plan.

What does the mesentery connect to?

A kind of: serous membrane.

Is the mesentery 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.
