fused sacrum in dogs
A collection of sacral vertebrae in the sacral region that are fused and part of the bony pelvis. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the fused sacrum is
A collection of sacral vertebrae in the sacral region that are fused and part of the bony pelvis. The atlas records it as a bone at the organ scale in the dog.
Where the fused sacrum is
It sits in the pelvis, back 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 fused sacrum connects to
The atlas records 9 typed relationships for it, across 4 kinds of connection. part of bony pelvis.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the fused sacrum. 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 os sacrum [vertebrae sacrales I - V], sacrum, sacrum [sacral vertebrae I - V], sacrum [sacral vertebrae I-V], os sacrum and sacral bone. Searching any of those names reaches this page.
