acetabular notch
The acetabulum presents below a deep notch, the acetabular notch, which is continuous with a circular non-articular depression, the acetabular fossa, at the bottom of the cavity: this depression is perforated by numerous apertures, and lodges a mass of fat. The notch is converted into a foramen by the transverse ligament; through the foramen nutrient vessels and nerves enter the joint; the margins of the notch serve for the attachment of the ligament of the head of the femur. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the acetabular notch is
The acetabulum presents below a deep notch, the acetabular notch, which is continuous with a circular non-articular depression, the acetabular fossa, at the bottom of the cavity: this depression is perforated by numerous apertures, and lodges a mass of fat. The notch is converted into a foramen by the transverse ligament; through the foramen nutrient vessels and nerves enter the joint; the margins of the notch serve for the attachment of the ligament of the head of the femur. The atlas records it as a bone at the organ scale in the human body.
Where the acetabular notch 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 acetabular notch connects to
The atlas records 5 typed relationships for it, across 4 kinds of connection. part of bone element and innominate bone.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the acetabular notch. 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.

Questions
Where is the acetabular notch?
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 acetabular notch connect to?
Part of: bone element and innominate bone.
Is the acetabular notch 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.
