sacro-iliac joint in dogs
The joint in the bony pelvis between the sacrum and the ilium of the pelvis, which are joined by strong ligaments. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the sacro-iliac joint is
The joint in the bony pelvis between the sacrum and the ilium of the pelvis, which are joined by strong ligaments. The atlas records it as a joint at the organ scale in the dog.
Where the sacro-iliac joint 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 sacro-iliac joint connects to
The atlas records 8 typed relationships for it, across 3 kinds of connection. part of anatomical entity, bony pelvis and pelvic girdle region.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the sacro-iliac joint. 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.
