postcranial axial skeleton

The postcranial subdivision of skeleton structural components forming the long axis of the vertebrate body; in Danio, consisting of the notochord, vertebrae, ribs, supraneurals, intermuscular bones, and unpaired median fins; in human consists of the bones of the vertebral column, the thoracic cage and the pelvis[ZFA+FMA]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the postcranial axial skeleton is

The postcranial subdivision of skeleton structural components forming the long axis of the vertebrate body; in Danio, consisting of the notochord, vertebrae, ribs, supraneurals, intermuscular bones, and unpaired median fins; in human consists of the bones of the vertebral column, the thoracic cage and the pelvis[ZFA+FMA]. The atlas records it as a system at the system scale in the human body.

Where the postcranial axial skeleton is

It sits within the skeletal system. Only the system is known. The position shown carries almost no spatial information.

What the postcranial axial skeleton connects to

The atlas records 16 typed relationships for it, across 4 kinds of connection. part of axial skeleton plus cranial skeleton and postcranial axial skeletal system.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the postcranial axial skeleton. 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 axial skeleton and post-cranial axial skeleton. Searching any of those names reaches this page.

Questions

Where is the postcranial axial skeleton?

It sits within the skeletal system. Only the system is known. The position shown carries almost no spatial information.

What does the postcranial axial skeleton connect to?

Part of: axial skeleton plus cranial skeleton and postcranial axial skeletal system.

Is the postcranial axial skeleton 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.
