pubic symphysis

The firm fibrocartilaginous joint in the median plane between the two opposing surfaces of the pubic bones, which are united by an interpubic disc of fibrocartilage as well as the superior and arcuate pubic ligaments. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the pubic symphysis is

The firm fibrocartilaginous joint in the median plane between the two opposing surfaces of the pubic bones, which are united by an interpubic disc of fibrocartilage as well as the superior and arcuate pubic ligaments. The atlas records it as a joint at the organ scale in the human body.

Where the pubic symphysis is

It sits in the pelvis and trunk, within the skeletal system. Positioned deliberately as part of this species body plan.

What the pubic symphysis connects to

The atlas records 10 typed relationships for it, across 5 kinds of connection. part of appendage girdle region, pelvic region of trunk and pubis.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the pubic symphysis. 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 symphysis pubis, interpubic articulation, symphisis pubis and symphysis pubica. Searching any of those names reaches this page.

Questions

Where is the pubic symphysis?

It sits in the pelvis and trunk, within the skeletal system. Positioned deliberately as part of this species body plan.

What does the pubic symphysis connect to?

Part of: appendage girdle region, pelvic region of trunk and pubis.

Is the pubic symphysis 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.
