costal diaphragm

The domain of the diaphragm that is a thin domed sheet of muscle composed of a radial array of myofibers extending laterally from the ribs and medially to a central tendon. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the costal diaphragm is

The domain of the diaphragm that is a thin domed sheet of muscle composed of a radial array of myofibers extending laterally from the ribs and medially to a central tendon. The atlas records it as a organ at the organ scale in the human body.

Where the costal diaphragm is

It sits in the thorax and trunk, within the muscular and respiratory 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 costal diaphragm connects to

The atlas records 5 typed relationships for it, across 3 kinds of connection. part of diaphragm and material anatomical entity.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the costal diaphragm. 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 costal part of diaphragm and pars costalis diaphragmatis. Searching any of those names reaches this page.

Questions

Where is the costal diaphragm?

It sits in the thorax and trunk, within the muscular and respiratory 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 costal diaphragm connect to?

Part of: diaphragm and material anatomical entity.

Is the costal diaphragm 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.
