postzygapophysis

Paired processes at the caudal end of the neural arch. The articular facets of the postzygapophyses face lateroventrally and articulate with the dorsomedially facing facets of the prezygapophyses of the succeeding vertebra. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the postzygapophysis is

Paired processes at the caudal end of the neural arch. The articular facets of the postzygapophyses face lateroventrally and articulate with the dorsomedially facing facets of the prezygapophyses of the succeeding vertebra. The atlas records it as a bone at the organ scale in the human body.

Where the postzygapophysis is

It sits within the skeletal system. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.

What the postzygapophysis connects to

The atlas records 5 typed relationships for it, across 3 kinds of connection. a kind of zygapophysis.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the postzygapophysis. 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 caudal articular process of vertebra, inferior articular process of vertebra, neural postzygopophysis, postzygapophysis, processus articularis inferior and processus articularis inferior vertebrae, and 6 more. Searching any of those names reaches this page.

Questions

Where is the postzygapophysis?

It sits within the skeletal system. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.

What does the postzygapophysis connect to?

A kind of: zygapophysis.

Is the postzygapophysis 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.
