sacral vertebra

A vertebra bone that is part of the sacral region of the vertebral column. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the sacral vertebra is

A vertebra bone that is part of the sacral region of the vertebral column. The atlas records it as a bone at the organ scale in the human body.

Where the sacral vertebra 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 sacral vertebra connects to

The atlas records 20 typed relationships for it, across 5 kinds of connection. part of abdominal segment of trunk, dorsum and postcranial axial skeleton, and 3 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the sacral vertebra. 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 sacral segment and segment of sacrum. Searching any of those names reaches this page.

Questions

Where is the sacral vertebra?

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 does the sacral vertebra connect to?

Part of: abdominal segment of trunk, dorsum, postcranial axial skeleton, sacral region, subdivision of vertebral column and trunk.

Is the sacral vertebra 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.
