acromion

Region of the scapula where the latter meets with the clavicle: attachment point of the clavicle to the scapula in some taxa. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the acromion is

Region of the scapula where the latter meets with the clavicle: attachment point of the clavicle to the scapula in some taxa. The atlas records it as a bone at the organ scale in the human body.

Where the acromion is

It sits 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 acromion connects to

The atlas records 5 typed relationships for it, across 5 kinds of connection. part of scapula.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the acromion. 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 acromion process, scapular acromion, acromion of scapula and acromion of the scapula. Searching any of those names reaches this page.

Questions

Where is the acromion?

It sits 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 acromion connect to?

Part of: scapula.

Is the acromion 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.
