innominate bone

A fused bone consisting of the ilium, ischium and pubis. Together with the sacrum and coccyx, it comprises the pelvis. [WP,modified]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the innominate bone is

A fused bone consisting of the ilium, ischium and pubis. Together with the sacrum and coccyx, it comprises the pelvis. [WP,modified]. The atlas records it as a bone at the organ scale in the human body.

Where the innominate bone is

It sits in the pelvis and trunk, within the skeletal system. 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 innominate bone connects to

The atlas records 28 typed relationships for it, across 4 kinds of connection. part of hip, material anatomical entity and pelvic girdle skeleton.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the innominate bone. 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

Questions

Where is the innominate bone?

It sits in the pelvis and trunk, within the skeletal system. 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 innominate bone connect to?

Part of: hip, material anatomical entity and pelvic girdle skeleton.

Is the innominate bone 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.
